The heaviest analogues of alkynes are investigated to realize a short triple bond between Pb atoms. For a short double bond between Pb atoms, the Pb2 molecule stabilized by dative N-heterocyclic carbenes is investigated. For unsupported and supported short bonds between transition metals, two-coordinate transition-metal and bicyclic four-membered ring complexes are investigated.

Abstract (R3P)2NiCl2 and LiP(SiMe3)2 react in a complex reaction sequence finally yielding (R3P)2Ni(PSiMe3)2 (5), containing a three-membered PNiP ring system, and [R3PNiP(SiMe3)2]2 (6), containing a (PNi)2 four-membered ring system with a nickel-nickel bond, respectively. NMR data are reported.

Abstract The photo-induced reaction between CpNb(CO)4 and Ph2P(CH2)2PR(CH2)2PPh2 (L; R = Ph, Cy) yields the chelated five-membered ring complexes cis-[CpNb(CO)2L] (two isomers in the case of R = Cy). The uncordinated PPh2 group reacts with CpNb(CO)3THF to form CpNb(CO)2(μ-L)CpNb(CO)3. IR, 31P and 93Nb NMR spectra are discussed and compared with corresponding data of the analogous vanadium complexes.
