Abstract: 
The effects of several mostly or-withdrawing, pi-donating substituents X on the hitherto unknown Bergman-like cyclizations of 3-substituted 1,4-pentadiynes were studied at the BLYP/6-311+G*//BLYP/6-31G* level of theory. As the cyclization with X = OH+ has the lowest barrier and is about thermoneutral, we predict that the title reaction is viable, for instance, through activation of derivatives with X = 0 with Lewis acids.
