Trial for anti-Markovnikov Hydration of 1-Decene Using Platinum Complexes Bearing a PBP Pincer Ligand, Inducing Alkene Isomerization and Decomposition of PBP Ligand

Mixing of [(PBP)PtCl] complex with 1-decene and H2O afforded isomerized alkenes. Deuterium-labeling experiment indicated the catalytically active hydride species for alkene isomerization formed from water and [(PBP)Pt] complex. Reaction of [(PBP)PtNTf2] with H2O gave a platinum hydride complex having PNNP ligand with a loss of boron atom, but the resulting complex showed low catalytic activity. Two types of cationic platinum hydride complexes were suggested as active species for alkene isomerization.
