Efficient macrocyclic olefin and en-yne metathesis can be conducted employing benzyl ester auxiliaries that engage in quadrupolar interactions. The use of amide linkers in place of esters results in higher overall yields. Computational studies sugges

The formation of various macrocyclic cyclophanes via ring-closing olefin metathesis is possible through the use of a pendant pentafluorobenzyl ester group. A quadrupolar interaction between the cyclophane core and the auxiliary is proposed to act as

2,3,4,5,6-Pentafluorobenzyl and 3,5-bistrifluoromethylbenzyl ester auxiliaries can enable difficult macrocyclizations to afford rigid all-carbon paracyclophanes. The effectiveness of these auxiliaries has been demonstrated in preparing the carbon ske

Efficient direct en-yne metathesis of strained macrocyclic systems is possible using highly active Grubbs-Hoveyda second-generation catalyst and when exploiting fluoroarene-arene gearing interactions. These interactions are effective even under high
