Conclusions
-
1.
A method for synthesis of trifluoromethylthiirane has been found which is based on the reaction of H2S with 1,1,1-trifluoro-3-chloropropane-2-sulfenyl chloride in N-methylpyrrolidone.
-
2.
Reactions of trifluoromethylthiirane with electrophilic (Cl2, HCl, CH3COCl) and nucleophilic (LiAlH4, Me2NH) reagents have been investigated, leading to 1,1,1-trifluoro-3-chloropropane-2-sulfenyl chloride, 1,1,1-trifluoro-3-chloro-2-propanethiol, 1-(trifluoromethyl)-2-chloroethyl thioacetate, 1,1,1-trifluoro-2-propanethiol, and 1,1,1-trifluoro-3-(N,N-dimethylamino)-2-propanethiol, respectively.
-
3.
The order of addition of sulfur monochloride to 1,1,1-trifluoropropene with the formation of bis-[1-(trifluoromethyl)-2-chloroethyl] disulfide has been established.
