摘要：

Eight, not six: The intramolecular frustrated Lewis pair 1 reacts with conjugated enynes and diynes by 1, 4-addition to yield the corresponding eight-membered cyclic allenes 2 and cumulenes 3, respectively. The thermodynamically more favorable 1, 2-addition (formation of six-mem bered-ring products) is not observed, which indicates that the observed addition is a kinetically controlled reaction.
