Formation of a Dicyanotriorganophosphorane from the Reaction of Triphenylphosphane with Phenylselenocyanate

A glimpse of the elusive: A Group 15 triorganodicyanide has been prepared and crystallographically characterized for the first time. The reaction of phenylselenocyanate with triphenylphosphane affords a facile route to the elusive dicyanotriorganophosphorane Ph3P(CN)2. The complex reaction mechanism...

Description
Summary:A glimpse of the elusive: A Group 15 triorganodicyanide has been prepared and crystallographically characterized for the first time. The reaction of phenylselenocyanate with triphenylphosphane affords a facile route to the elusive dicyanotriorganophosphorane Ph3P(CN)2. The complex reaction mechanism also results in formation of the diiminophosphorane Ph3PNC(CN)2C(CN)2NPPh3.
