A palladium-catalyzed three-component reaction of aryliodides, norbornenes, and hexamethyldisilane/hexamethyldigermane has been developed for the assembly of highly functionalized disilanes/digermanes. The potential synthetic utility of this methodology was highlighted by the late-stage manipulations of natural products and the iterative C–H bis-silylation for the synthesis of highly decorated arenes

Cycloaddition reactions of N-allyl substituted polycyclic derivatives of isoindole-1,3-dione with nitrones proceeds regio- and stereoselectively on the double bond of the N-allyl substituent giving substituted isoxazolidines with good yields. Regioselectivity of the cycloaddition of this dipolarophiles with nitrile oxides depends on the structure of unsaturated hydrocarbon scaffold and the reaction
