expected for free GeH(2); rather, the transient is assigned to an intramolecular Ge(II)-alkene π-complex of one of the isomeric substituted hydridogermylenes derived from a solvent-cage reaction between GeH(2) and its diene (6) coproduct, formed by addition of HGe-H across one of the C=C bonds. These conclusions are supported by the results of DFT calculations of the thermochemistry associated with π-complexation
Highly regio- and stereoselective formation of allylamines has been achieved through a three-component reaction between iodobenzene, an allene, and an amine in acetonitrile, catalyzed by in situ formed and by isolated palladium-diphosphine catalysts.

An efficient, one-pot method for the conversion of carbonyl electrophiles to allylicchlorides has been developed, by activating magnesium alkoxides in situ using TiCl4.
The synthesis of cyclic allylborates was achieved by the reaction of 1,3-dienes and B2pin2 using a copper catalyst. The cyclic allylborate could be used in several organic transformations such as regioselective protonation, the allylation of electrophiles, and Suzuki–Miyaura coupling.
