Hydrosilylation titanium catalysed

Trimethylsilane in the presence of palladium gives 1,4-dihydro-1-trimethylsilylpyr-idine, together with silylated dimer titanium-catalysed hydrosilylation produces a tetrahydro-derivative cleanly. ... 

As well as rhodium-catalysed hydrosilylation, asymmetric ruthenium and titanium-catalysed hydrosilylation have also been reported. Amongst these, Buchwald s report of the hydrosilylation of ketones using titanocene catalysts and inexpensive polymethyUiydrosiloxane (PMHS) appear to be the most general. 

Scheme 5.11 Titanium-catalysed hydrophosphination and hydrosilylation reactions...

E)-l-Trimethylsilyl-l-alkenes are available by chloroplatinic acid catalysed hydrosilylation of 1-alkynes. These vinyl silanes react with dichloromethyl methyl ether in the presence of titanium(iv) chloride at low temperature to give a/S-unsaturated aldehydes. Alkenyl silanes with the silyl group in a non-terminal position also give the corresponding a/8-unsaturated aldehyde (Scheme 50). " ...
