WebThe four activated azide/[Ru]/alkyne complexes have been modeled for all their possible conformers and were classified using the Maxwell–Boltzmann distribution. The local electrophilicity and nucleophilicity indices, based on Parr functions, have been calculated for the terminal sites of the benzyl azide and the carbon atoms of the internal alkynes. WebThe synthesis of several methyl and benzyl γ-ylidenetetronates was accomplished and the bromination reactions of these derivatives, using bromine or N ... The copper(I) catalyzed cycloaddition reaction of N-Boc propargyl amine (dipolarophile) 1 with benzyl azide (1,3-dipole) 2 was found to proceed smoothly in t-BuOH/H2O at room ...
