WebJan 8, 2015 · Why is C=C IR active? I understand that in order for an bond to IR active, there needs to be a change in the dipole moment of the bond. This excludes Cl-Cl etc non-polar molecules. I can never see any reference to a C-C (single) bond absorption, but there is a C=C absorption (also a C-C triple). In short, why does any C-C bond - and especially ... WebJan 12, 2024 · The selective formation of compounds 1–3 is remarkable since only a few (low-valent) main group species were found to activate DCM and chloroform via simple C–Cl bond insertion, i.e. neutral stannylenes, 19 germyliumylidene, 20 phosphenium cations, 21 and silylenes, 22 while such reactivity was not yet observed towards carbon tetrachloride.
