The Abnormal Hydrolysis of 7-Phosphanorbornenium Salts: A Case of Phosphonium-Phosphenium Equivalence
The hydrolysis of a phosphanorbornenium triflate gives the expected tertiary phosphine oxide by cleavage of one P-C bond of the bridge in the presence of triethylamine but affords the secondary phosphine oxide by cleavage of the two P-C bonds of the bridge in the presence of alpha-picoline.
