  Photochemical synthesis and stereodynamic behavior of alkoxy-bridged (silylene)(germylene)iron complexes

  摘要：

  Mixed (silylene)(germylene)iron complexes have been synthesized for the first time and are internally stabilized by a donor bridging alkoxy group: [Cp'(CO)Fe{GeMe2--O(R)--SiMe2}] (CP'= C5Me5; R = Me, Bu(t)). Two-dimensional and variable-temperature H-1 NMR spectroscopies establish germylene-methyl group exchange. Computer simulation of the spectra and calculation using the Eyring equation yield values for DELTA-G(double dagger)298 for the process of 62 kJ mol-1 (R = Me) and 61 kJ mol-1 (R = Bu(t)). A mechanism involving cleavage of the Ge--O partial bond, followed by rotation of the resulting coordinated germylene moiety about the Fe=Ge double bond, is proposed for this exchange. The (silylene)(germylene)iron complexes are weighted toward the (methoxysilyl) (germylene) form, indicating that germylene ligands are more stable than their silicon analogues.

  Thermal reactions of 1,2-dimetallacyclohexa-3,5-dienes (1–3) with tetracyanoethylene (TCNE) were investigated. The reaction of 1,2-disilacyclohexa-3,5-diene (1) with TCNE mainly gave 4-amino-5,6-dicyano-2,2,11,11-tetramethyl-1,8,9,10-tetraphenyl-3-aza-2,11-disilatricyclo[6.2.1.03,7]undeca-4,6,9-triene through a charge-transfer complex. The reaction of 1,2-digermacyclohexa-3,5-diene (2) with TCNE afforded
