Upon an increase in temperature and lattice dilation, covalent Pb 6s and Br 5p antibonding interactions at VBM are weakened, lowering the VBM potential energy, while the CBM potential energy changes slightly. As a net effect, Eg increases [21]. Under the latter assumption, the large temperature...

However, the produced 1,4-dienyl trialkylsilanes cannot be applied to sequential transformations such as Hiyama coupling without activation by a strong base because of their low reactivity. In this context, we achieved regioselective anti-allylindation of simple alkynes using InBr3 and allylic ...
