The benzannulation reaction of Fischer carbenecomplexes is investigated under conditions where the reaction of the carbenecomplex is occurring in the presence of two different alkynes. A series of competition experiments are examined where the effects of various structural factors are explored by pitting 10 different carbenecomplexes with 11 different alkynes. Terminal alkynes will react selectively
