Double C−H Activation on Osmium and Ruthenium Centers: Carbene vs Olefin Products
摘要:
Cyclometalation of bis(di-tert-butylphosphino)pentane ((DBPP)-B-t) and subsequent product dehydrogenation take place in reactions of (DBPP)-B-t with [OsCl6](2-) and [RuCl2(p-cymene)](2) to give the M(IV) dihydrides, MH2Cl[CH(C2H4PBu2t)(2)], and the (alkylidene)osmium and (olefin)ruthenium complexes OsHCl[=C(C2H4PBu2t)(2)] and RuHCl[(Bu2PCH2CH2)-P-t((E)-CH=CH)CH2PBu2t].
