Preparation, Structural Analysis, and Reactivity Studies of Phosphenium Dications
This work expands on the recent synthesis and reactivity of the two-coordinate P(III)-containing dication [((Ph3P)2C)P(NiPr2)]2+ (3a2+). Two additional dications of general formula [((RPh2P)2C)P(NR′2)]2+ (3b2+, R = 1/2 ...
Oxidation of a P-C Bond under Mild Conditions
The reactivity of phosphenium dication [(Ph3P)2C-P-NiPr2]2+, 12+, towards pyridine N-oxide (O-py) has been investigated. The resulting oxophosphonium dication [(Ph3P)2C(NiPr2)P(O)(O-py)]2+, 22+, was surprisingly stabilized ...
