摘要:
The iminophosphine-phosphazene [P-III-P-V] heterocyclic adduct [IPr center dot PN(PCl2N)(2)] was prepared via reduction of the cyclic phosphazene [Cl2PN](3) in the presence of the carbene donor IPr {IPr = [(HCNDipp)(2)C:], where Dipp = 2,6-(Pr2C6H3)-Pr-1}. By contrast, the treatment of [Cl2PN](3) with the N-heterocydic olefin IPr=CH2 yielded the olefin-grafted phosphazene ring [(IPr=CH)P(Cl)N(PCl2N)(2)].
