1,3-Dipolar cycloaddition of in situ generated C,N-diaryl nitrilimines to 2-methyl-2-vinyl oxirane gives rise to the regioselective formation of novel 5-(2-methyloxiranyl)-4,5-dihydropyrazole derivatives in moderate to good yields. The structures and ster

Spiropyrazolines have been synthetized by 1,3-dipolar cycloaddition of some 2-arylidene-1-tetralones with diarylnitrilimines.It is shown that ring-closure reaction is regiospecific.The diastereoselectivity of the reaction is strongly dependent on the conf

Irradation of 2,5-diaryl-2H-tetrazoles in an EPA-glass (ether: i-pentan: ethanol = 5:5:2) or in an i-pentan glass at 77-80 K with UV-light of wavelength 290 nm yields diarylnitrilimines by the extrusion of nitrogen.The photoreactions investigated show spe
