platinum at 80 1C. Our catalyst exhibited excellent performance
in mediating the hydrosilylation of these olefins by polysilox-
anes, as well as tri and di-alkoxy silanes (Table 1, entries 1–3
and 5–11), however, decreased activity was exhibited with the
trialkyl silane, 4d (Table 1, entries 12–15). In the case of the
hydrosilylation of 5e by MD’M (Table 1, entry 4), low product yield
was not accompanied with significant byproduct formation.
Additionally, we found that the substrate vinylcyclohexene oxide
proceeded ideally at 60 1C with MD’M as product degradation
was observed at higher temperatures (Table 1, entry 2).
This body of work demonstrates the successful application
of a highly-active hydrosilylation catalyst that can be prepared by
a relatively simple and straightforward method of preparation.
This success is marked not only by its efficiency, but by its
operability under common industrial conditions as well as its
scope of functionality to relevant substrates. We plan to continue
our evaluation of this system in other synthetically challenging
applications that currently employ platinum-based catalysts.
