The mechanism of the reaction of 1-trichlorostannyl-2,3-butadiene with formaldehyde involving SnCl4 and DMF has been studied by using the density functional method at the B3LYP/6-31G** level. The structures and energies of the stationary points were calculated to produce the activation barriers. The transition states were confirmed by using vibration analysis and IRC calculations. Two reaction pathways were obtained and discussed. The results show that the reactions take place with high regioselectivity and mainly produce the product of the reaction of the 1-trichlorostannyl-2,3-butadiene with formaldehyde involving DMF, in good agreement with the available experiments.

Key words: 1-trichlorostannyl-2,3-butadiene, formaldehyde, DMF, SnCl4, B3L YP
