Abstract
The chloroplatinic acid-catalysed hydrosilylations of phenylacetylene, 1-heptyne, and 1-octyne by (eta(5)-C5H5)Fe(CO)(2)SiPh(2)H (I), Ph(2)M eSiH and PhMe(2)SiH have been studied in the presence of CO. The resul ts indicate that the normally high levels of trans-beta-addition produ cts formed in the absence of CO are dramatically reduced in favour of the alpha-addition products.
