A green and sustainable electrochemical hydroboration of various alkynes with HBpin has been reported for the first time. Under catalyst-free and additive-free mild reaction conditions the corresponding alkenyl boronic esters were obtained in good to excellent yields within 30 min at room temperature. A plausible reaction mechanism was proposed based on the corresponding experiments. Download : Download
A practical synthetic method for the synthesis of vinyl sulfonyl fluorides through copper-promoted direct fluorosulfonylation has been developed. The reaction of the vinylboronic acids with DABSO and then NFSI is performed under mild reaction conditions. This transformation efficiently affords aryl or alkyl vinyl sulfonyl fluorides with good reaction yields, exclusive E-configuration, broad substrate

Facile synthesis of vinyl boronateesters via dehydrogenative borylation of terminal alkenes was accomplished by employing a recyclable cobalt-metal–organic framework (MOF) catalyst and dimethylformamide (DMF) solvent as a hydrogen scavenger. This process avoids using special ligands, high temperatures, long reaction time, and additional hydrogen acceptors and can be carried out in air. A wide range
