Abstract

Dehydrogenative borylation of alkenes and 1, 3-dienes was realized by carrying out the reaction in the presence of bis (pinacolato) diboron (B 2 pin 2) and a catalytic amount of PSiP-pincer palladium complex. This protocol has the following notable features. 1) Monoanionic nature of the PSiP-pincer ligand prevents the formation of boryl (hydrido)-or dihydridopalladium species, enabling synthesis of various vinyl-or dienylboronic esters in ...
