<p>One facile and efficient strategy for the hydrosilylation of steric 1,1-disubstituted
terminal alkenes is demonstrated. Investigations on substrate scope and control
experiments revealed the necessity of thioether in promoting this process under
a simple iridium catalysis system. This convenient and feasible method is
expected to be useful in the synthesis of sulfur-containing organosilicon
polymers with different side-chains.</p><p><br></p>
