A novel Pd(II)-catalyzed vinylic C-H activation and cyclization has been developed, reacting a series of small, medium, and large N-acetyl hydrazones of acylcycloalkenes with vinyl azides to access diverse cycloalkeno[c]-fused pyridine scaffolds. This protocol provides progress in C(sp2)-H bond activation of medium to large cycloalkenes, and the target products can be obtained in a specific regioselectivity with good functional group tolerance and a broad substrate scope.
Friedel-Crafts Reactions of Some Vinyisilanes

Substituted cyclohexenylsilanes (2), (5), (9), and (13) undergo Friedel-Crafts reactions to give substitution products, site-selectively at the carbon atom carrying the trimethylsilyl group. β-Trimethylsilylstyrene (17) similary gives more substitution in Friedel-Crafts reactions with benzoyl chloride and with phenylacetyl chloride than styrene itself.The syntheses of the silanes are reported, and some limitations of the idea identified.
