摘要: The addition of dichlorocarbene to cyclopropene has been studied with direct dynamics quasiclassical trajectories using B3LYP/6-31G*. yielded 1,1-dichlorobicyclo[1.1.0]butane and 1,1-dichloro-1,3-butadiene in a ratio 4.7:1, which is consistent the experimental 4:1. large majority formed products within 100 fs start trajectory proceeded concerted manner bicyclobutane or butadiene; no zwitterion biradical intermediate was observed. Eight generated subsequently dissociated chloride form an ion pair, recombined 2,3-dichlorocyclobutene. lifetime pair averaged 95 fs, too short be considered intermediate, previous calculations that characterized as transition state. This study lends strong support proposition CCl2 controlled by dynamic effects. Copyright © 2011 John Wiley & Sons, Ltd.
