Abstract

In principle, both the addition to give the silirane and the subsequent opening could be either cis or trans. Although the details of the ring opening remain to be established, it does not seem reasonable to postulate a trans addition of the silylene to the olefin. Silylenes are singlet ground state^,^.^^^^'^ and a sensible expectation is that we are seeing the silicon counterpart of the known cis addition of singlet carbenes6
