Possible π-complex intermediates in the reaction of disilenes with mercury(II) trifluoroacetate
Abstract
The reaction of mercury(II) trifluoroacetate with disilenes (3) and (4a,b) in tetrahydrofuran at 25 °C produces 1,2-bis(trifluoroacetoxy)disilanes (5) and (6a,b); below –15 °C, n.m.r. spectra indicate that an intermediate is formed, for which structures (7) and (8a,b) are proposed.
