Cyclohexylacetylene is used in the preparation of hydrido-vinylidene complexes of osmium, which finds vital intermediates in several homogeneous and heterogeneous catalytic reactions such as alkene olimerization, polymerization and Fischer-Tropsch synthesis.
Cyclohexylacetylene (Ethynylcyclohexane) was used in the preparation of [Os[(E)-CH=CHR](=C=C=CPh2)(CH3CN)2(P(i)Pr3)2]BF4 (R = Ph, Cy).
Cyclohexylacetylene (Ethynylcyclohexane) mediates NADPH-dependent loss of cytochrome P-450 on incubation with hepatic microsomes.
