Attempts to trap P-tert-butyl substituted phosphaalkene complexes 66c-e with 2,3-dimethylbutadiene have been unsuccessful, owing to the poor reactivity of the diene at low temperatures. This limitation is circumvented when the respective f-butyl-substituted complexes are exposed to electron-rich acyclic dienes such as l-methoxy-l,3-butadiene, l-(trimethylsilyloxy)- ,3-butadiene, and l-methoxy-3-(trimethylsilyloxy)-...
