| Popis: | The chloroplatinic acid-catalysed hydrosilylations of phenylacetylene, l-heptyne, and l-octyne by ( η 5 - C 5 H 5 )Fe(CO) 2 SiPh 2 H (I), Ph 2 MeSiH and PhMe 2 SiH have been studied in the presence of CO. The results indicate that the normally high levels of trans -β-addition products formed in the absence of CO are dramatically reduced in favour of the α-addition products. |
