摘要

Abstract Both molybdenum (VI) dichloride dioxide (MoO 2 Cl 2) and its dimethylformamide (DMF) complex catalyze the addition of alcohols to isocyanates giving carbamates. Most additions proceeded to completion at room temperature within 20 min using as little as 0.1 mol% of the catalyst when working on a 1-mmol scale or just 100 ppm working on a 20- mmol scale. Sterically encumbered substrates reacted to completion when 1 mol% of the ...
