Racemic and optically active 1,1′-binaphthyl-2,2′-diyl sulfite: Synthesis, crystal structure, and ring-opening reactions with selected nucleophiles
Preparation of the sulfite derived from racemic and (R)-(+)-enantiomer of BINOL is reported. The crystal structure of the optically active, levorotatory sulfite isomer and its ring opening induced by nucleophilic substitution reactions with selected nucleophiles are presented.

Cationic and radical intermediates in the acid photorelease from aryl sulfonates and phosphates
The irradiation of a series of phenyl sulfonates and phosphates leads to the quantitative release of acidity with a reasonable quantum yield (≈0.2). Products characterization, ion chromatography analysis and potentiometric titration are consistent with the intervening of two different paths in this reaction, viz. cationic with phosphates and (mainly) radical with sulfonates.

Simple, rapid procedure for the synthesis of chloromethyl methyl ether and other chloro alkyl ethers
Zinc(II) salts catalyze the reaction between acetals and acid halides to provide haloalkyl ethers in near-quantitative yield. Reactions from millimole to mole scale are typically complete in 1-4 h with 0.01 mol % catalyst. The solutions of haloalkyl ethers thus obtained can be utilized directly in reactions in which the presence of the ester byproduct does not interfere. Excess haloalkyl ether is destroyed on workup, thereby minimizing exposure to this class of carcinogenic compounds.

A mild method for conversion of alcohols to dialkyl sulfites by use of Na2SO3/SOCl2
Alcohols are easily converted to their corresponding dialkyl sulfite under mild reaction conditions using Na2SO3/SOCl2 in moderate to good isolated yields.

Reactions of N-sulfinylfluoroalkanesulfonyl amines with nucleophiles containing reactive hydrogen
The reactions of N-sulfinylfluoroalkanesulfonyl amines, RfSO2NSO (1), with malonate or dialkyl phosphite gave 1:1 adducts RfSO2NHS(O)Nu , and with alcohols or phenols formed RfSO2NH2 and the sulfites O=S(OR)2 by double addition .Trans-sulfinylation occurred during the reaction of 1 with anilines (C6H5NH2, 4-FC6H4NH2 and C6F5NH2).

ORGANOSULPHUR COMPOUNDS-LXIX OPTICALLY ACTIVE SULPHINATES: A NEW TYPE OF ENANTIOSELECTIVE ASYMMETRIC SYNTHESIS AND KINETIC RESOLUTION
Optically active sulphinates with the sulphur atom as a sole centre of chirality are prepared by two methods.The first involves the reaction of symmetrical sulphites with tert-butylmagnesium chloride in the presence of optically active aminoalcohols.This new asymmetric, enantioselective synthesis affords t-butylsulphinates with 40-70percent enantiomeric excess values.The second approach is based on a new type of kinetic resolution taking place when racemic sulphinates are reacted with tert-butylmagnesium chloride complexed by optically active alkaloid bases.Both the recovered sulphinates and sulphoxides formed in this reaction show moderate optical purities.
