Platinum-catalyzed aromatic C-H silylation of arenes with 1,1,1,3,5,5,5-heptamethyltrisiloxane

The intermolecular dehydrogenative coupling of 1,1,1,3, 5,5,5-heptamethyltrisiloxane with arenes proceeded in the presence of a catalytic amount of platinum complexes prepared in situ from PtCl2 and hydrotris(pyrazolyl)borate derivatives.
