Abstract :
The 1:2 and 1:1 reactions of cis-[tBu(H)NP(μ-tBuN)]2 (1) with paraformaldehyde afforded α-aminophosphonates, cis-[tBu(H)NCH2(O)P(μ-tBuN)]2 (2) and cis-[tBu(H)NP(μ-tBuN)2P(O)CH2N(H)tBu] (3), respectively, through the insertion of a methylene moiety into the P–N bonds. The X-ray crystal structure of 2 reveals that the insertion reaction occurs selectively at the exocyclic P–N bonds of bis(amido)cyclodiphosphazane.
