Glycosylation of benzenesulfinic acid with 1,2-dibromides was carried out using silver triflate as the promoter, and gave sulfinate esters as products by reaction at oxygen rather than at sulfur. The sulfinate esters were obtained as mixtures of stereoisomers at the stereogenic sulfur atom. ...

aThe products formed in the addition reaction ofn-butyllithium with excess DPE in benzene were characterized by size exclusion chromatography, electrospray mass spectrometry (ESI MS) and NMR spectroscopic techniques. The products were the monoadduct nBuDPEH (1,1-diphenylhexane) and the diadduct, nBu...
