The present invention relates to a novel fluorinating agent. Fluoroalkylamines are known as fluorinating agents that can convert alcoholic hydroxyl groups to fluorine. This is the Yarovenko reagent or the Farr reagent (diethylamine adduct of monochlorotrifluoroethylene:
(C 2 H 5 ) 2 NCF 2 CHFCl). Compounds into which fluorine atoms have been introduced using such fluorinating agents are useful in many fields due to their chemical stability, chemical resistance, weather resistance, water and oil repellency, physiological effects, etc. have. In particular, the present inventor has discovered that N,N-dialkyl-3-oxo-3-alkyl-trifluoropropylamine of the following general formula is a dialkylamine adduct of an alkyl trifluorovinyl ketone synthesized using trifluoroethene as a starting material. However, it has been found that the present invention is a fluorinating agent that effectively fluorinates alcohol. General formula: (However, R 1 , R 2 and R 3 are the same or different alkyl groups.) The above propylamine according to the present invention is particularly suitable for the first
It has the effect of effectively fluorinating benzyl alcohol among the primary alcohols, and also fluorinating most of the secondary alcohols and tertiary alcohols, which will be described in detail later. In the present invention, examples of R 1 , R 2 , and R 3 include methyl groups, ethyl groups, propyl groups, isopropyl groups, butyl groups, isobutyl groups, etc., each having 10 or less carbon atoms (even 5 or less). . The fluorinating agent according to the present invention will be illustrated below. First, this fluorinating agent will be explained according to its manufacturing method. For example, 4-chloro-3 as starting material,
When 4,4-trifluoro-2-butanone 1 is reacted with 2 equivalents of diethylamine as shown in the following formula, methyl trifluorovinyl ketone 2 is obtained as an intermediate product by diethylamine, and diethylamine is further added to this by Michael addition. Add by reaction. By this, the desired N,N-diethyl-3-oxo-3-methyl-1,2-difluoropropenylamine 3 and N,N-diethyl-3-oxo-3-methyl-1,1, 2-trifluoropropylamine (or N,N-diethyl-
3-oxo-1,1,2-trifluorobutylamine) 4 are produced, respectively. CH 3 COCHFCF 2 Cl 1 (C 2 H 5 ) 2 NH/n hexane――――――――――――→ Room temperature, 1 hour [CH 3 COCF=CF 2 ] 2 (C 2 H 5 ) 2 NH ――――――――→ CH 3 COCF=CFN(C 2 H 5 ) 2 3 +CH 3 COCHFCF 2 H(C 2 H 5 ) 2 4 In this reaction, the above products 3 and 4 are converted from 1 85
However, in the product, 3 (also known as enamine) accounts for more than 99%, and 4 is produced in only a small amount. The product was liquid (bp 82-83°C/2mmHg) and the following analytical data were obtained. 3 (E form): NMR F (bonded to C on the COCH 3 side): Chemical shift 107.5 (d) F (bonded to C on the N(C 2 H 5 ) 2 side): δ28.1 Coupling constant 103.3Hz 3 ( Z form): NMR F (bonded to C on the COCH 3 side): Chemical shift 95.5 (d, q) Coupling constant 11.1Hz Coupling constant with H of CH 3 CO 5.5
Hz F (N (C 2 H 5 ) bonded to C on the 2 side): 9.4 ppm (d, d, d) H (COCH 3 ): Chemical shift δ2.12, 2.08 Coupling constant 5.5 Hz H (CH 3 ): Chemical shift: 1.23 H(N(C 2 H 5 ) 2 : Coupling constant: 3.8, 2.8 Hz Starting material 1 can be synthesized with a yield of 82% according to the following formula: CF 2 =CFHCH 3 COCl− AlCl 3 /CH 2 Cl 2 ――――――――――――――――――――――――→ Room temperature, 2 days CH 3 COCHFCF 2 Cl 1 Next, as above, Using the obtained enamine 3 containing a trace amount of 4, attempts were made to fluorinate various alcohols.As a result, among the above products, 4
was found to be a fluorine source (fluorinating agent) that contributes to fluorination. This will be explained in detail below. When the alcohol to be fluorinated is a normal primary alcohol other than benzyl alcohol, the desired fluorinated product cannot be obtained at all, and an unsaturated compound 5 as shown in the following formula is quantitatively produced. This is a major difference from Farr's reagent (FAR reagent: (C 2 H 5 ) 2 NCF 2 CHFCl), which is a conventional fluorinating agent. R−OH+(C 2 H 5 ) 2 NCF 2 CHFCOCH 3 4 Room temperature, 20 minutes――――――――→ (C 2 H 5 ) 2 O (C 2 H 5 ) 2 NC(OR)=CFCOCH 3 5 ( 19 FNMR yield ~100%) However, as R-OH, C 2 H 5 OH, n-
C 8 H 17 OH and (CH 3 ) 3 CCH 2 OH were used, respectively. However, in the case of benzyl alcohol, the method 4 produces dibenzyl ether as a by-product, but produces a fluorinated product of benzyl alcohol (PhCH 2 F) in a relatively good yield. In addition, the two examples shown in the table below
With respect to primary and tertiary alcohols, fluorination occurs according to the following formula in the same manner as in conventional Farr reagents using 4 above, and the corresponding fluorinated product 6 is obtained.

By following the 19 FNMR spectrum, it was found that the reaction progressed through an intermediate product (C 2 H 5 ) 2 NC(OR)'=CFCOCH 3 5. In this case, as described in 4 above, the fact that two fluorine atoms are bonded to the carbon atoms adjacent to the nitrogen atom contributes to the production of the above intermediate product and further promotes the fluorination of the alcohol. it is conceivable that. In addition, in the above example, the starting material 1
The methyl group of or the ethyl group of diethylamine can be replaced with other alkyl groups (particularly those having 10 or less carbon atoms: corresponding to R 1 , R 2 , and R 3 in the above-mentioned general formula). Further, other secondary or tertiary alcohols can be used as the alcohol to be fluorinated. It will be understood that the above examples can be modified in various ways based on the technical idea of the present invention. Next, specific examples of the present invention will be described. Example 1 4-chloro-3,4,4-trifluoro-2-

In this reaction, the above product was obtained in a good yield of 85%, but the former (also known as enamine) accounted for more than 99% of the product, and the latter was only produced in a small amount. It was not done. The product was liquid (bp 82-83°C/2mmHg) and the following analytical data were obtained. 3 (E form): NMR F (bonded to C on the COCH 3 side): Chemical shift 107.5 (d) F (bonded to C on the N(C 2 H 5 ) 2 side): δ28.1 Coupling constant 103.3Hz 3 ( Z form): NMR F (bonded to C on the COCH 3 side): Chemical shift 95.5 (d, q) Coupling constant 11.1Hz Coupling constant with H of CH 3 CO 5.5

I tried. As a result, 4 of the above products
was found to be a fluorine source (fluorinating agent) that contributes to fluorination. When benzyl alcohol was selected as the alcohol to be fluorinated and the above product was reacted with it, dibenzyl ether was produced as a by-product, but the fluorinated product of benzyl alcohol (PhCH 2 F) was produced in a relatively good yield. (reaction time 0.2 hours, yield 56%). Examples 2 to 5 In Example 1, the alcohols shown in the table below were selected as alcohols to be fluorinated and fluorinated in the same manner, and the results shown in the table were obtained.
