Zirconium-Catalyzed Synthesis of Alkenylaminoboranes: From a Reliable Preparation of Alkenylboronates to a Direct Stereodivergent Access to Alkenyl Bromides

A simple procedure has been optimized for the preparation of alkenylaminoborane from alkynes using diisopropylaminoborane and HZrCp2Cl. Coupled with a magnesium-catalyzed dehydrogenation, it allowed for the use of air- and moisture-stable diisopropylamine. This synthesis has been extended to a one-pot sequence leading directly to bromoalkenes with controlled stereochemistry. As such, it provides an easy, scalable, cheap process to access alkenylboronates and both (E)- and (Z)-bromoalkenes from commercially available alkynes.

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.

Synthesis of B-protected β-styrylboronic acids via iridium-catalyzed hydroboration of alkynes with 1,8-naphthalenediaminatoborane leading to iterative synthesis of oligo(phenylenevinylene)s

Hydroboration of aromatic and aliphatic alkynes with 1,8- naphthalenediaminatoborane ((dan)BH) proceeded in the presence of [IrCl(cod)]2 complex with a DPPM or DPEphos ligand, affording alkenylboronic acids whose boronyl groups are masked by th
