Regioselective C–H Activation Preceded by Csp2 –Csp3 Reductive Elimination from Cyclometalated Platinum(IV) Complexes

Reductive elimination reactions of the cyclometalated platinum(IV) compounds [PtMe2Cl{C6H4CHNCH2(4-ClC6H4)}L] and [PtMe2Br{C6H4CHNCH2(C6H5)}L] (L = SMe2, PPh3) to form Csp3 –Csp2 bonds, followed by either exclusive Csp2 –H bond activation (L = SMe2) or competition between Csp2 –H and Csp3 –H bond...

Description
Summary:Reductive elimination reactions of the cyclometalated platinum(IV) compounds [PtMe2Cl{C6H4CHNCH2(4-ClC6H4)}L] and [PtMe2Br{C6H4CHNCH2(C6H5)}L] (L = SMe2, PPh3) to form Csp3 –Csp2 bonds, followed by either exclusive Csp2 –H bond activation (L = SMe2) or competition between Csp2 –H and Csp3 –H bond activation (L = PPh3), are reported. Isomerization to give endo products instead of the expected exo complex was observed for the ligand C6H4CHNCH2(2-BrC6H5), and formation of an endo six-membered platinacycle occurs for the ligand 2,4,6-Me3C6H2CHNCH2(2-BrC6H4).
