Platinum complex-catalyzed hydrosilylation of 2,2-diaryl-1-methylenecyclopropane affording (silylmethyl)cyclopropane

PtI2(PPh3)2-catalyzed hydrosilylation of 2,2-diphenyl-1-methylenecyclopropane with HSiEt3 forms (2,2-diphenylcyclopropyl)methyl(triethyl)silane in 87% yield as a sole product. This highly selective addition of SiH bond converts 2,2-diaryl-1-methylenecyclopropane into its silylated derivative without ring-opening.
