A highly efficient palladium-catalyzed oxidative cross-coupling of arylhydrazines and arenethiols with molecular oxygen as the sole oxidant to afford unsymmetrical diaryl sulfides has been developed. The only byproducts are nitrogen and water. A broad range of functional groups, even the reactive iodides, are tolerated and thus offer the opportunity for further functionalization.

An unprecedented sulfenylation reaction of carbon-boron bonds has been developed using sulfonyl hydrazides as sulfenyl sources. A range of sulfonyl hydrazides underwent tetrakis(acetonitrile)copper(I) tetrafluoroborate [Cu(CH3CN)4BF4]/2,2′-bipyridine-catalyzed sulfenylation with boronic acids under air to give structurally diverse thioethers in moderate to good yields. Preliminary mechanistic studies show that sulfonyl hydrazides are subjected to decomposition into thiosulfonates and disulfides followed by formation of carbon-sulfur bonds with boronic acids.
