Soluble trans-Di-1-alkynyl- and Poly-trans-ethynyl(tetraalkylphthalocyaninato)metal IVB Derivatives

The hitherto unknown peripheric substituted trans-dihalogeno(tetra-tert-butylphthalocyaninato)metal IVB derivatives 5a,b and 6a,b as well as trans-dichlorogermanium (6c) were converted into the monomeric, soluble trans-di-1-alkynyl(tetra-tert-butylphthalocyaninato)metal IVB compounds 10a - h and trans-di-1-alkynylgermanium compounds 10i - l, respectively, by the reaction with various 1-alkynyl Grignard derivatives 9a - e.The high solubility of all products in organic solvents and the strong ring-current effect of the macrocycle on the axial ligands are remarkable.The formally analogous reaction with the bidentate ethynediyldi-Grignard compound 9f leads to the soluble, acetylene-bridged polymers 12a - c.These are considered as model compounds for a new kind of one-dimensional conductors proposed by us.
