  Synthesis and Reactivity Studies of 2,4-(Dimethylmethano)-2,4-didehydroadamantane: A Comparison with an Unsubstituted Analog

  摘要：

  We prepared 2,4-(dimethylmethano)-2,4-didehydroadamantane (1), agem-dimethyl[3.1.1]propellane, and systematically examined its chemical behavior in relation to its unsubstituted analogue 2,4-methane-2 ,4-didehydroadamantane (2). 2,4- (Dimethylmethano)-2,4-didehydroadamantane (1) was obtained in 70% yield by pyrolysis of the dry lithium salt of the tosylhydrazone derived from 4-isopropylidene-2-adamantanone (6) in vacuo. Propellane 1 is thermally more stable than 2, but its reactivity is considerably greater than that of 2. It is highly reactive toward electrophiles and free radicals. Propellane 1 also reacts with alcohols, dienes and oxygen but is less susceptible to polymerization than 2. Enhanced chemical reactivity of dimethyl[3.1.1]propellane 1, with respect to its unsubstituted analogue 2, is in accord with an increase in nucleophilicity of its central bond due to electron donation of the methyl groups.
