Part I, The Hofmann Rearrangement. First-order rate constants and activation parameters were determined for the rearrangement of eleven N-halogenoamides. The structures of the N-halogenoamides (RCO.NHX) differed in the leaving group (X = chlorine or bromine) and the migrating group (R=ethyl, isopropyl, t-butyl, diphenylmethyl, benzyl, phenyl or p-tolyl). N-Bromoamides and the corresponding N-chloroamides rearranged at similar rates. When the leaving group was changed from bromide to chloride the...
