Boron, (Diphenylphosphine)trihydro

First Examples of C─P Cross-Coupling Reaction of Vinyl Tosylates with Diphenylphosphine Derivative: New Access to Vinylphosphine-boranes

“…Knowing that vinyl tosylates are less reactive than the corresponding vinyl triflates, the reactions were performed with diphenylphosphine-borane 1, which is a well-known reactive phosphine derivative. 9 Indeed, both phenyl and borane groups are able to activate the P H bond of the phosphine.…”
