Halogen bridgehead

The synthesis begins with the halogenation of adamantane (74) with bromine to give 76 or chlorine and AlClg to give 75. The four bridgehead positions... [Pg.18]

The effect of structure on relative reactivity may be seen particularly clearly when a halogen atom is located at the bridgehead of a bicyclic system. Thus the following rates were observed for solvolysis in 80% aqueous ethanol at 25° ... [Pg.86]

However, electrooxidation of 1-bromoada-mantane involves the transfer of more than three electrons to afford Af-(1-adamantyl)acetamide. In a comparable study of the oxidation of 2-haloadamantanes and their methyl-substituted analogues [13], it was observed that the products depend upon the identity of the halogen atom as well as the number of bridgehead methyl groups. [Pg.220]

Seminal PES studies of the cycloalkyl halides have dealt with the interactions of halogen lone-pair (np) orbitals with the skeletal orbitals ([Pg.152]
