Truly Multifunctional Heterocycle: Iminophosphorane, N,P Chelate, and Dihydropyridine

Three in one: The anellated σ4‐1λ5‐[1,3,2]diazaphosphole 2 exists in tautomeric equilibrium with isomer 1 (see scheme) and undergoes three completely different types of reaction: trimethyl aluminum binds at the N terminus of the PN bond with ring retention, the dihydropyridine fragment reacts with...

Description
Summary:Three in one: The anellated σ4‐1λ5‐[1,3,2]diazaphosphole 2 exists in tautomeric equilibrium with isomer 1 (see scheme) and undergoes three completely different types of reaction: trimethyl aluminum binds at the N terminus of the PN bond with ring retention, the dihydropyridine fragment reacts with an activated acetylene in a pseudo‐[2+2] cycloaddition, and PN bond cleavage is possible with RhI.
