摘要:
Strategies for the construction of TMS-protected first generation star and dendritic polyynes, which are subsequently metallated to give multiple CO2C2(CO)(6) clusters, are reported. In the absence of crystallographic data, well-resolved C-13 NMR spectroscopy is a powerful technique for confirming the presence of core, inner and peripheral cluster domains. (C) 2006 Elsevier Ltd.
