The stereoselective “inter-intra” cascade carboalumination of dienes and trienes with Et2AlCl and Ti(OPr-i)4 provides a novel and stereoselective route to five- and six-membered rings including fused-, bridged-, and spiro-bicyclic structures with generation of quaternary carbon centers.

the ability to switch the actual function of the catalyst and resulting products. Here we report such an example of multi-dimensional catalysis. Featuring an easily prepared, bench-stable cobalt(I) hydride complex in conjunction with pinacolborane, we can switch the reaction outcome between two widely employed transformations, olefin migration and hydroboration, with visible light as the trigger.
