Conjugate additions of O-silylated acetals to simple enones have been reported to proceed without a catalyst if acetonitrile is used as solvent. Inability to repeat this procedure led to the discovery that an as yet unknown species formed from P4O10 in acetonitrile displays high catalytic activity.
