Notes:
Additions of phenylchlorocarbene and phenylfluorocarbene to representative alkynes are rapid (106-107 l mol-1 s-1). The variation of the rate constants with alkyne structure parallels that observed with analogous alkene substrates. The addition of phenylchlorocarbene to 3-hexyne is characterized by a very low activation energy (∼ 2 kcal mol-1) and a large, negative entropy of activation (∼ -20 e.u.).
