Linear Mixed-Metal Pd(4-n)Ptn (n = 0—2) Tetranuclear Complexes Supported by Imino-bridged Tetraphosphines, rac-dpmppan

摘要

We have reported linear octapalladium chains by using methylene–bridged tetraphosphine dpmppm, [Pd8(meso/rac–dpmppm)4(L)2](BF4)4 (L = CH3CN, dmf, dpmppm = Ph2PCH2P(Ph)CH2P(Ph)CH2PPh2), and recently prepared an imino—bridged tetra- phosphine, rac-dpmppan (Ph2PCH2P(Ph)N(Ph)P(Ph)CH2PPh2), which afforded a linear tetrapalladium complex, [Pd (rac-dpmppan) (XylNC) ](PF ) (1).
