Abstract
Titanium-catalysed dehydrocondensation and hydrosilylation of primary, secondary and tertiary phenyl- 27 silanes have been investigated in a one-pot process with Cp2Ti(OPh)2 as catalyst by NMR studies. Only 28 primary and secondary silanes were found to undergo simultaneous dehydrogenative coupling and 29 hydrosilylation reactions to produce the functional polysilanes.
