has been isolated in 73% yield from the reactionbetween 1-phenylphosphirane and methyl triflate in benzene. The crystal and molecular structures of 1 have been determined. The phosphiranium ion in 1 undergoes ring opening with water to give (±)-ethylmethylphenylphosphine oxide, and reacts with primary alcohols to give (±)-alkoxyethylmethylphenylphosphonium ions. Treatment of 1 with dimethyl- or methylphenylacetylene
