We developed the regioselective anti-carbometalation of alkynyl sulfides via the use of InBr3 and organosilicon nucleophiles to give β-mercaptoalkenylindium compounds. The structure of β-mercaptoalkenylindium was characterized by X-ray crystallographic analysis. A variety of disubstituted alkenyl sulfides were regio- and stereoselectively obtained by either halogenation or Pd-catalyzed cross-coupling with aryl halides using the mercaptoalkenylindiums.

Gold-catalyzed oxidations of thioalkynes with 8-methylquinoline oxides afford 2-phenylthioketenes that can be trapped efficiently with alcohols. The synthetic utility is manifested by terminal and internal thioalkynes over a wide scope, bearing esters, ke

The retro-Favorskii reaction is an excellent way to achieve terminal alkynes. Methodologies that connect the synthesis of terminal alkynes and organochalcogen motifs are important for the construction of novel compounds. Fourteen new terminal alkynes containing either Csp?S or Csp?Se bonds were selectively prepared through the retro-Favorskii reaction from the respective carbinol precursors. It was discovered that terminal chalcogen alkynes were stable for weeks if stored as a solution in hexanes.
NUCLEOPHILIC REACTION AT A VINYL CENTER. XXII. SYNTHESIS AND NUCLEOPHILIC VINYLIC SUBSTITUTION IN E-β-FLUOROVINYL ARYL SULFONES

The reaction of potassium fluoride with E-β-bromovinyl aryl sulfones in the presence of 18-crown-6-ether leads to a mixture of the sulfones XC6H4SO2CH2CHF2 and E-XC6H4SO2CH=CHF, the ratio of which decreases in the order X=CH3, H, Cl, NO2.The kinetics of n
