Attempted tandem allylic acetate isomerisation and ring-closing metathesis using combinations of palladium(0)/Grubbs' catalyst/PPh 3 led to either allylic isomerisation or ring-closing metathesis but not both in tandem. The effect was traced to deactivation of Grubbs' catalyst by added PPh 3 and poi
