Abstract Complete regioselective 1, 6-hydrosilylation of dimethyl cis, cis-muconate took place by using trialkylsilanes in the presence of RhCl (PPh 3) 3 as a catalyst. The novel, functionalized ketene silyl acetal thus obtained exhibited moderate electrophilic properties. Hydrosilylation of trans, trans-muconate under similar conditions gave only a 3, 4-adduct, whereas that of trans, cis-muconate resulted in a complicated mixture of adducts but for a ...
