A Ru(II)-catalyzed C–H alkenylation of benzimidates with unactivated alkenes providing ortho-alkenylated benzonitriles in good to excellent yields in a highly regio- and stereoselective manner is described. In the reaction, an imidate group converted into a nitrile under the reaction conditions. The alkenylation reaction was compatible with various substituted benzimidates as well as functionalized

to a cascade reaction to give unexpected 2-substituted 2,3-dihydro-1H-indenimines which, upon treatment with t-BuOK, rearrange to 2-vinylbenzonitriles in high overall yields. This simple procedure represents a new approach to the synthesis of aromatic nitriles via isocyanide–cyanide interconversion.
