（I） (II）
R in the Formulas I1For any one in hydrogen, halogen radical, alkoxy.
Above-mentioned reaction temperature can be non-exclusively 40oC、50oC、60oC、70oC、80oC、90oC、100oC or 120oC, it is excellent
Choosing is 80 DEG C；Reaction time in non-limiting manner can be small for 10 hours, 12 hours, 14 hours, 16 hours, 18 hours or 24
When, preferably 12h, or reaction time can also detect the residual quantity of raw material is how many and true by gas chromatograph-mass spectrometer or TLC
The fixed suitable reaction time；Above-mentioned halogen similar nature, can select any one in-F ,-Cl ,-Br ,-I；And alkoxy
CH can then be selected3O-、C2H5O-、C3H7O-、C4H9O-、C5H11O-、C6H13Any one in O- etc. saturation alkoxies.
Further, the persulfate reagent is any one in potassium peroxydisulfate, sodium peroxydisulfate.
Further, the reaction dissolvent is acetonitrile, DMF（DMF）, ethanol, dimethyl sulfoxide (DMSO)
（DMSO）, ethanol, in acetone at least any one.Preferably dimethyl sulfoxide (DMSO).
Further, the acetylenic ketone compounds and the mol ratio of fluoroform sulfane alcohol silver compound are 1:1.5.It is non-limiting
Property can be 1:1、1:1.2、1:1.5、1:1.8 or 1:2.0, preferably 1:1.5.
Further, the acetylenic ketone compounds and the mol ratio of HMPA stabilizer are 1:0.1.
Further, the acetylenic ketone compounds and the mol ratio of persulfate are 1:1-5.Can be 1 in non-limiting manner:
1、1:2、1:3、1:4 or 1:5, both preferred mol ratios are 1:3-5.
Further, the post processing after reaction terminates comprises the following steps, after completion of the reaction, with Rotary Evaporators from reaction
Solvent is removed in the mixture obtained after end, residue obtains target product, post layer with the purification of 300-400 mesh silica gel column chromatography
Analysis process can determine suitably to elute terminal with TLC tracing and monitorings.
Another object of the present invention is to provide it is a kind of as obtained by above-mentioned preparation method with trifluoromethylthio
Indanone compounds, it is characterised in that comprising-SCF3Functional group, chemical structural formula is as follows：
R2For hydrogen.Wherein, R2It can also be alkyl, alkoxy, halogen radical etc..
Using such scheme, synthetic method of the invention is with acetylenic ketone compounds and fluoroform sulfane alcohol silver compound
