Epub 2016 Dec 13.Toward the preparation of a coordination complex of the heterodiatomic molecule PN, P≡N-V(N[tBu]Ar)3 (1, Ar = 3,5-Me2C6H3), we report the use of ClPA (A = C14H10, anthracene) as a formal source of phosphorus(I) in its reaction with Na[NV(N[tBu]Ar)3] (Na) to yield trimeric cyclo-triphosphane [PNV(N[tBu]Ar)3]3 (3) with a core composed exclusively of phosphorus and nitrogen. In the presence of NapS2 (peri-1,8-naphthalene disulfide), NapS2P-NV(N[tBu]Ar)3 (6) is instead generated in 80% yield, suggesting trapping of transient 1. Read More
