摘要：

The anaerobic reduction of the dichlorotitanium(IV) porphyrins (OEP)TiCl2 and (TTP)TiCl2 (OEP = octaethylporphyrinato, TTP = meso-tetra-p-tolyl-porphyrinato) with LiAIH4 in the presence of diphenylacetylene in toluene produces the pi-alkyne Ti(II) adducts (OEP)Ti(eta-2-PhC = CPh) (1) and (TTP)Ti(eta-2-PhC = CPh) (2). The structure of 1 has been determined by single-crystal X-ray diffraction analysis. Complex 1 crystallizes in the centrosymmetric space group C2/c with a = 49.369 (7) angstrom, b = 13.734 (9) angstrom, c = 36.042 (5) angstrom, beta = 136.62 (1)-degrees, V = 16784 (9) angstrom 3, Z = 16, R = 0.061, and R(W) = 0.063. The asymmetric unit of 1 contains two molecules. Alkyne C-C distances and Ti-alkyne distances are 1.30 (1) (C27-C28), 2.016 (5) (Ti1-C27), 2.015 (5) (Ti1-C28), 1.30 (1) (C61-C62), 2.007 (7) (Ti2-C61), and 2.028 (7) angstrom (Ti2-C62).
