Carbide Bridged Complexes [HB(pz)(3)(OC)(3)Mo C-Pt(PPh3)(2)Br], [(TPP)Fe C-M(CO)(4)-M(CO)(5)] (M = Mn, Re), [(TPP)Fe=C=Cr(CO)(5)], (TPP)Fe=C=Fe(CO)(4)] (pz=3,5-dimethylpyrazol-l-yl; TPP = Tetraphenylporphyrinate) from Halogeno-Carbyne and -Carbene Complexes [1]

摘要

The reaction of the bromocarbyne complex [HB(pz)(3)(OC)(2)Mo C-Br] with [(Ph3P)(2)Pt(eta(2)-C2H4)] at room temperature affords the dimetallapropene [HB(pz)(3)(OC)(2)Mo=C(Br)-Pt(PPh3)(2)] complex. At higher ternperature the isomeric carbide bridged complex [HB(pz)(3)(OC)(2)Mo C-Pt(PPh3)(2)Br] is formed. From the tetraphenylporphyrinato-dichloro-carbene-iron complexes [(TPP)Fe=CCl2] with the carbonyl metallates Na[Re(CO)(5)], Na[Mn(CO)(5)], Na-2[Cr(CO)(5)] and Na[Fe(CO)(4)] the carbide bridged complexes [(TPP)Fe C-M(CO)(4)-M(CO)(5)] (M = Mn, Re), [(TPP)Fe=C-Cr(CO)(5)] and [(TPP)Fe=C= Fe(CO)(4)] have been obtained. Instead of TPP also tetrakis(p-methoxyphenyl)porphyrinate and tetrakis(p-cyanophenyl)porphyrinate have been used.
