The first syntheses of <I>N</I>-(2,4,6-cycloheptatrienyl)iminophosphoranes (<B>3a</B>, <B>b</B>) and their thermal conversion to <I>N</I>-(1,3,5-cycloheptatrienyl)iminophosphoranes (<B>5a</B>,<B>b</B>) have been studied. The kinetic study of the 1,5-hydrogen migration of <B>3a</B>,<B>b</B> to <I>N</I>-(1,3,6-cycloheptatrienyl)iminophosphoranes (<B>4a</B>,<B>b</B>) has also been investigated. The reaction of <B>5b</B> with α-bromoacetophenone derivatives has provided a novel route to the 1-azaazulene ring system, albeit in low yields.
