Easy activation : A Lewis acid catalyst based on molybdenum relies on activation by molecular oxygen for its high catalytic activity. The novel complex catalyzes the aza‐Diels–Alder reaction of acyl hydrazones with Danishefsky dienes (see scheme) and other Lewis acid mediated reactions, such as the Mukaiyama aldol addition, Mannich‐type reactions, and the addition of trimethylsilylcyanide to imines.
