Abstract
1,132,701. 3,4-Dihydro-2H-pyran-2-yl derivatives. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17 Feb., 1966 [16 Feb., 1965], No. 6655/65. Heading C2C. Novel organic phosphorus compounds of the formula where R 1 and R 3 , alike or different, are hydrogen, hydrocarbon or substituted hydrocarbon, R 2 is hydrogen, hydrocarbon, substituted hydrocarbon or, where R 1 is H, may be a 3,4- dihydro-2H-pyran-2-yl radical, R 4 is hydrogen, hydrocarbon, substituted hydrocarbon or 3,4- dihydro-2H-pyran-2-methyl, R 5 is hydrogen, hydroxyl or -OR, and R 6 is hydroxyl or-OR, R being a hydrocarbon, or substituted hydrocarbon radical, provided that where R 1 and R 2 , or R 3 and R 4 , represent hydrocarbon or substituted hydrocarbon they may be joined either directly or through a further atom or group of atoms so as to form with the carbon or nitrogen atom to which they are attached the residue of a cyclic compound, and, provided that at least one of R 2 and R 4 is or contains a 3,4-dihydro- 2H-pyran-2-yl radical, are prepared by reacting an aldehyde or ketone of formula (R 1 )(R 2 )C = O with an equimolecular mixture of an amine of formula (R 3 )(R 4 )-N-H and a substituted phosphorus acid or ester of formula (R 5 )(R 6 )(H)P=O, preferably under an inert atmosphere, or, by reacting an aldimine or ketimine of formula (R 1 )(R 2 )C=N.R 4 which contains at least one 3,4-dihydro-2H-pyranyl radical with the appropriate phosphorus acid or ester preferably under an inert atmosphere to give a compound of the given general formula in which R 3 is hydrogen. Specified substituents optionally carried by hydrocarbon groups include halogen, alkoxy, carboalkoxy, hydroxy, nitro, amino and substituted amino groups, and the 3,4-dihydro-2H-pyran-2-yl radicals may also carry substituents in the pyran ring, particularly alkyl or halogen groups. Amines which may be used as starting materials include primary and secondary amines, diamines, polyamines and amine-terminated polyoxyalkylenes. Aldimine starting materials may include compounds of the formula where R 2 is H, R 4 is as above and B is the residue of an aldehyde of formula where B is a bivalent organic radical.
