Does trans 1,3-dichlorocyclobutane have zero dipole moment?

WebTransition structures for the syn and anti attack of diazomethane on cis-3,4-dichlorocyclobutene have been obtained with the HF/3-21 G model. These calculations correctly predict the dominance of syn attack. Analysis of the activation energy shows that the inherent facial bias of dichlorocyclobutene is reflected, at the transition state, in the … WebPredicted data is generated using the US Environmental Protection Agency s EPISuite™.
