Coordination chemistry of ene-1,1-diamines and a prototype "carbodicarbene"

(Chemical Equation Presented) Carbophilic Lewis acids can polarize a coordinated π-bond by a slippage mechanism. A series of stable ylid- or enolate gold complexes of ene-1,1-diamines not only emulate this property, but also reveal the exceptional donor capacity of such electron-rich olefin ligands. Moreover, the first metal complex of a tetraaminoallene is reported, which features a prototype "carbodicarbene" ligand bound to a transition-metal template.

GEAR EFFECT-10 CONFORMATIONAL ASPECTS OF THE POSITIVE OR NEGATIVE BUTTRESSING EFFECTS OF METHYL GROUPS: POLYMETHYLPYRIDINES

The effects of the shape of a methyl group on reactivity, which cannot be accounted for by considering a methyl group as a spherical subtituent with the appropriate van der Waals radius, was considered in kinetics of alkylation of substituted pyridines and barriers to rotation and ground state conformations of an isopropyl group attached to a planar framework.The perturbation of a methyl group by an o-methyl group is accounted for by a unique conformational explanation which involves the polyhedral shape of the methyl group.
