A novel ammonium iodide-promoted arylsulfonylation of quinones with sodium arylsulfinates has been explored. This reaction proceeded smoothly through unique nucleophilic addition reaction and produced the arylsulfonylation products in moderate to good yields. The reactions proceeded efficiently over a broad range of substrates with good regioselectivity and functional group tolerance.
Metal-free sulfonylation of quinones with sulfonyl hydrazides in water: Facile access to mono-sulfonylated hydroquinones

This paper describes a simple and practical protocol for the direct synthesis of monosulfonylated hydroquinones through a transition-metal-free cross-coupling between quinones and sulfonyl hydrazides in water. The procedure tolerates a variety of quinones
Selectivity adjustment in the cleavage of allyl phenyl and methyl phenyl ethers with boron trifluoride-methyl sulfide complex

Cleavage of model allyl phenyl and methyl phenyl ethers with boron trifluoride-methyl sulfide complex is described. The demonstrated strong dependence of the reaction rate on the substitution pattern of the phenyl ring and the reaction conditions make it potentially possible to selectively cleave a single methoxy (or allyloxy) group in poly methoxy (or allyloxy) compounds.

A series of polyhydroxylated phenyl vinyl sulfones was prepared by phase transfer condensation of suitable phenyl methyl sulfones with substituted benzaldehydes. The compounds were prepared as structural analogs of biologically active chalcones. One of the compounds was cyclized to a derivative of 2,3-dihydro-2-phenyl-1,4-benzoxathiin-4,4-dioxide, a heterocyclic system closely resembling flavanones.
