Abstract

The phosphenium ion [(i‐Pr~2~N)CIP]^+^ (1) reacts with crotonaldehyde dimethylhydrazone (2) to afford a product with a C~3~NP ring system (4). The reaction of 1 with acetone azine (3) results in a novel tricyclic compound (6) which features a C~2~N~2~P~2~ and two C~2~N~2~P rings. The structures of 4 and 6 were established by X‐ray crystallography. Compound 4, C~12~H~26~AlCl~3~N~3~OP, crystallizes in the monoclinic space group __P__2~1~/n with Z = 4, a = 15.400(6), b = 14.442(4), c = 9.206(3) Å, and β = 93.33(3)°. Compound 6, C~12~H~22~Al~2~Cl~6~N~4~O~2~P~2~, crystallizes in the triclinic group __P__1 with Z = 1, a = 8.556(1), b = 9.782(1), c = 8.119(1) Å, α = 94.48(1), β = 104.97(1), and γ = 78.35(1)°.
