Platinum nanoparticles supported on titania efficiently catalyzed the diboration of alkynes and alkenes under solvent-and ligand-free conditions in air. The cis-1,2-diborylalkenes and 1,2-diborylalkanes were obtained in moderate to excellent yields following, in most cases, a simple filtration workup protocol. The versatility of the cis-1,2-diboronvinyl compounds was demonstrated in a series of organic transformations, including the Suzuki-Miyaura cross coupling and the boron-halogen exchange. Click diboration: The diboration of alkynes and alkenes catalyzed by platinum nanoparticles on titania is shown to take place under solvent-and ligand-free conditions in air. The 1,2-diboronvinyl compounds are obtained with exclusive cis stereochemistry and are subjected to different useful chemical transformations.
