The hydroformylation of norbornene catalysed by [Pt(C2H4)(dppb)]/CH3SO3H (dppb = 1,4-bis(diphenylphosphino)butane) occurs under standard oxo conditions giving the exo-norbornanecarboxaldehyde exclusively. The deuteroformylation of this olefin shows that the addition of H and CHO groups is cis. As for the chemoselectivity of the monohydroformylation of 2,5-norbornadiene, the catalytic system affords better results than the more common catalytic precursors of rhodium and platinum/tin complexes; the regioselectivity towards the exo-aldehyde is lower. © 1993.

Abstract

The hydroformylation of norbornene catalysed by [Pt(C2H4)(dppb)]/CH3SO3H (dppb = 1,4-bis(diphenylphosphino)butane) occurs under standard oxo conditions giving the exo-norbornanecarboxaldehyde exclusively. The deuteroformylation of this olefin shows that the addition of H and CHO groups is cis. As for the chemoselectivity of the monohydroformylation of 2,5-norbornadiene, the catalytic system affords better results than the more common catalytic precursors of rhodium and platinum/tin complexes; the regioselectivity towards the exo-aldehyde is lower. © 1993.
