Polystyrene-g-boramine random copolymers are dihydrogen reservoirs with tunable dehydrogenation temperatures, which can be adjusted by selecting the boramine content in the copolymers. They display a unique dihydrogen thermal release profile, which is a d

We report herein the synthesis of functionalized styrenes via palladium-catalyzed Suzuki–Miyaura cross-coupling reaction between aryl ketone derivatives and potassium vinyltrifluoroborate. The employment of pyridine-oxazoline ligand was the key to the cleavage of unstrained C[sbnd]C bond. A variety of functional groups and biologically important moleculars were well tolerated. The orthogonal Suzuki–Miyaura coupling demonstrated the synthetic practicability.

A versatile and efficient method to prepare borylated arenes furnished with alkyl, alkenyl, alkynyl, aryl, and heteroaryl functional groups is developed by merging Ir-catalyzed C-H borylations (CHB) with a chemoselective palladium-catalyzed cross-coupling of triorganoindium reagents (Sarandeses-Sestelo coupling) with aryl halides bearing a boronic ester substituent. Using triorganoindium cross-coupling reactions to introduce unsaturated moieties enables the synthesis of borylated arenes that would be difficult to access through the direct application of the CHB methodology. The sequential double catalyzed procedure can be also performed in one vessel.

Methylthioether is involved in the methylthiotransfer process in organisms, and therefore its functionality is of paramount importance to living organisms. Several methods for the installation of the methylthio group in small molecules have been reported previously; however, procedures starting from unactivated alkenes are rare. Herein, we report a formal hydro/deuteromethylthiolation of alkenes by using dimethyl(methylthio)sulfonium trifluoromethanesulfonate as the stimulator and sodium borohydride/deuteride as the hydrogen/deuterium source. The process represents a mild, transition metal-free and methanethiol-free route towards the synthesis of methylthioethers from unactivated alkenes. This journal is
