metathesis product 3fa has been structurally unambiguously authenticated by single-crystal X-ray crystallography. The ortho substitution displays, consistently, an inferior reaction outcome as compared to the para counterpart. Thus, a methyl group (1g) affords a 29% yield; a methoxy group (1h) delivers a 34% yield; a fluorine group (1i) imparts a 30% yield. For the meta substitution, the reactivity for a methyl-bearing substrate (1j, 31%) is intermediate between that of the para and ortho analogs; a methoxy group (1k, 34%) imparts an essentially identical reactivity as the ortho analog; a chlorine substituent (1l) diminishes the yield to 23%. The metathesis reaction is also tolerant of para, meta disubstitution. The reactivity from methyl disubstitution (1m, 33%) stays the same as that from the para substitution.
