Conversion of trifluoromethyl groups into nitrile functions during cyclization of hexafluoroiodoalkanes with sodium amide
摘要:
The cyclization of (CF3)2CHCH2CIR1CHR2R3 (1) (1a: R1 = Me, R2 = R3 = H; 1b: R1 = H, R2 = R3 = Me; 1c: R1 = R2 = H, R3 = Bu) with sodium amide occurs with conversion of trifluoromethyl groups to cyano functions or with their replacement by hydrogen atoms.
