hypervalentcompounds. These are species in which there are more atoms attached to a centralatomthan can be accommodated by an octet of electrons. An example is sulfur hexafluoride, SF6, for which writing a Lewis structure with six S―F bonds requires that at least 12 electrons be present ...

Lewis acid catalyzed addition reactions of alkyl halides 1 with unsaturated hydrocarbons 2 have been studied. 1:l addition products 3 are formed if the addends 1 dissociate faster than the corresponding products 3; otherwise, polymerization of 2 takes place. For reaction conditions under which 1 ...
