Ru-Catalyzed Dehydrogenative Silylation of POSS-Silanols with Hydrosilanes: Its Introduction to One-Pot Synthesis
journal contribution
posted on 2019-01-10, 21:04 authored by Joanna Kaźmierczak, Krzysztof Kuciński, Dariusz Lewandowski, Grzegorz HreczychoA commercially available and stable
ruthenium dodecacarbonyl catalyst
(Ru3(CO)12) allows very efficient and convenient
access to functionalized silsesquioxanes (SQs) containing siloxane
moiety (Si–O–Si) via dehydrogenative coupling of POSS-silanols
with hydrosilanes. With the aid of SiH-containing silsesquioxanes,
an unprecedented one-pot procedure has been revealed, and the usefulness
of this approach was demonstrated by the synthesis of various derivatives
via O-silylation, as well as CC and CN hydrosilylation.
