Comparison of the efficiencies of oxidative coupling reactions for different molybdenum(V)‐based systems.16

Compound		Yield [%][a]
		MoCl5 [c]	MoCl5/TiCl4 [d]	1 [e]
		47	41	60
		67	44	82
		34	<5[b]	78

[a] Yields of isolated products. [b] Yield determined by GC. [c] 2.2 equiv of MoCl₅. [d] 1.4–2.2 equiv of both MoCl₅ and TiCl₄. [e] 0.7–1.1 equiv of 1.
