  Facile Cycloreversion of Octacarbonyl-1,2-diosmacyclobutane: Convenient Source of the Os2(CO)8 Unit in the Formation of 1,2-Diosmacyclobutenes

  摘要：

  Cycloreversion of octacarbonyl-1,2-diosmacyclobutane, Os2(CO)8(mu-eta1:eta1-CH2CH2) (1), can be affected by mild thermal (T > 28-degrees-C) or photochemical (lambda > 330 nm) activation. In the presence of activated alkynes the reaction affords 1,2-diosmacyclobutenes in moderate to good yields, Os2(CO)8(mu-eta1:eta1-RCCR') (R = R' = CO2Me (2a), Ph (2b); R = H, R' = CO2Me (2c), C(O)Me (2d)). Compounds 2 have been characterized by IR and NMR spectroscopies. The C-13 NMR spectra indicate that the molecules are static at room temperature with regard to CO exchange processes. A detailed preparation of 1 is reported as well.
