Rhodium-catalyzed dehydroborylation of styrenes with Naphthalene-1,8- diaminatoborane [(dan)BH]: New synthesis of masked β-borylstyrenes as new phenylene-vinylene cross-coupling modules

Styrene derivatives underwent dehydroborylation with naphthalene-1,8- diaminatoborane [(dan)BH] in the presence of a cationic rhodium complex, giving β-borylstyrene derivatives in good yields. Thus prepared β-borylstyrenes bearing a chlorine or B(pin) group on their aromatic rings were utilized for the synthesis of highly conjugated molecules through stepwise cross-coupling, taking advantage of the dan group as an effective protective group for a boronyl group.
