Synthesis of [1′-(diphenylthiophosphoryl)ferrocenyl]ethyne and alkyne-metal complexes thereof
摘要:
The novel functionalized ferrocene, alkyne Ph2P(S)fcC CH (1; fc = ferrocene-1,1'-diyl) was synthesized from Ph2P(S)fcCHO (6) via the Corey-Fuchs reaction. It was further reacted with K-2[HgI4]KOH to give mercury(II) acetylide Hg{C CfcP(S)Ph-2}(2) (8), and with [Co-2(CO)(8)] to afford the trimetallic CO2Fe complex [(mu-eta(2): eta(2)-1){Co(CO)(3)}(2)](Co-Co) (9). All compounds were characterized by spectral methods (IR, NMR, and MS) and by combustion or high-resolution MS elemental analyses. In addition, the crystal structures of 1, Ph(2)PfcBr (5), 6, Ph2P(S)fcCH=CBr2 (7), and 9 were determined by single-crystal X-ray diffraction. (c) 2006 Elsevier B.V. All rights reserved.
