Metal vapour synthesis of phospha-organometallic compounds via reaction of cobalt atoms with the phospha-alkyne tBuCP: synthesis and structural characterisation of the sandwich compounds [Co(η5-P3C2tBu2)(η4-P2C2tBu2)], [Co(η5-P2C3tBu3)(η4-P2C2tBu2)] and the protonated tetraphospha-barrelene complex [Co(η4-P4C4tBu4H)(η4-P2C2tBu2)], the latter as its [W(CO)5] adduct
摘要:
The reaction of cobalt atoms with ' BuC dropP gives the sandwich compounds [Co(eta (5)-P3C2' Bu-2)(eta (4)-P2C2' Bu-2)] and [Co(eta (5)-P2C3' Bu-3)], which have both been structurally characterised by single crystal X-ray diffraction studies. The novel P2C3' Bu-3)(eta (4)-P2C2' Bu-2)] protonated tetraphospha-barrelene complex [Co(eta (P4C4)-P-4' Bu4H)(eta (4)-(P2C2Bu2)-Bu-')] is also formed in the reaction and has been structurally characterised as its [W(CO)(5)] adduct. Variable temperature NMR spectra of these complexes are reported and discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
