Since Wittigs pioneering studies on phosphorus-ylides,ylides have continuously attracted more and more interest of scientists.In our previous work [1,2],the regions of positive electrostatic potentials(σ-holes) have been found in ylides CH2XH3(X = P,As,Sb) and CH2YH2(Y = S,Se,Te),on the outer surfaces of group VA and VIA atoms,approximately along the extensions of the C-X and C-Y bonds,respectively.
