type (CF3)2N·C⋮CR [where R = H, Br, CF3, or N(CF3)2] at ca, 90° to give high yields of 1 : 1 adducts. The structures of the adducts have been assigned on the basis of their i.r., n.m.r., and mass spectra. The symmetrical acetylene [R = N(CF3)2] forms only one adduct, perfluoro(2-methyl-4-dimethylamino-2,5-diazahex-4-en-3-one)(CF3)2N·CO·C(:N·CF3)·N(CF3)2, but the acetylenes (R = H, Br, or CF3) give

Photochemical reactions of N-bromobistrifluoromethylamine with cis- or trans-but-2-ene gives the 1:1 adducts erythro- and threo-2-bromo-1-methyl-NN-bistrifluoromethylpropylamine in the ratios 17:83 and 77:23, respectively. The corresponding N-chloro-amine reactions afford the erythro- and threo- 1:1 adducts in the ratios 10:90 and 87:13, respectively. A thermal reaction of the N-bromo-amine with 1
