The palladium-catalysed reactions of 2-iodobenzamides 1–5 with trimethylsilyl acetylene 6 led to 2-(2-trimethylsilyl)ethynyl benzamides 7–11 in excellent yields. The 2-(2-trimethylsilyl)ethynyl benzamides 7–11 underwent Friedel-Crafts reactions with acid chlorides 12–17 or anhydride 18 smoothly under mild conditions yielding the 3-alkylidene isoindolin-1-ones 19–38.
