Abstract
Reactions of tripropyl- and tributylphosphines with methoxyallene were studied. In the case of tripropylphosphine, a mixture of tripropylphosphine oxide and tripropyl-1-formylethylidenephosphorane (the latter in equilibrium with itsO-betaine) was obtained. The reaction with tributylphosphine yields, along with tributylphosphine oxide, two homologous ylides, namely, tributyl-1-formylethylidene- and tributyl-1-formylpropylidene-phosphoranes, which are also in equilibria with theirO-betaines. A possible scheme of formation of these ylides is discussed.
