Abfangreaktionen für unbeständige [1‐Chlor‐2,2,2‐trifluor‐1‐(trifluormethyl)ethyl]dialkylphosphite

Trapping Reactions for Unstable [1‐Chloro‐2,2,2‐trifluoro‐1‐(trifluoromethyl)ethyl] Dialkyl Phosphites The reaction of ClP(OR) 2 1a–d (R = Me, Et; R–R = CH 2 CH 2 , CMe 2 CMe 2 ) with hexafluoroacetone yields the thermally unstable phosphites ClC(CF 3 ) 2 OP(OR) 2 4a–d besides other products. Trimethyl phosphite converts 4a–d into the phosphates (MeO) 2 P(O)OC(CF 3 ) 2 P(OR) 2 (R = Me, Et) 5a and b and the phosphonates (MeO) 2 P(O)C(CF 3 ) 2 OP(OR) 2 (R–R = CH 2 CH 2 , CMe 2 CMe 2 ) 5c and d , Compounds formed in an Arbuzov reaction.
