Metal carbonyl derivatives of ?-cyclopentadienyltricarbonyls of manganese and rhenium

Technetium and Rhenium

“…381 ' 382 Through appropriate subsequent reactions the lithiated intermediate can be converted to a variety of ring-substituted products as listed in Table 9. [338][339][340]343,344 Significantly, with change in the solvent to diethyl ether, nucleophile is directed to carbon of coordinated CO; with [Re(CO) 3 Table 10 except for the vinylidene complex which is presented in Table 14 below and the dinitrogen complexes which are further discussed in Chapter 60. The dimer (62), noted as a minor product in Scheme 21, is observed in greater yield during photolysis of [Re(CO)3(r;-Cp)] in hexane; the dimer yields equimolar quantities of the parent and the phosphine-substituted complex upon reaction with PPI13 (equation 43).…”

Synthesis of [Re2(CO)8{μ-N2(C5H4)2}], Derived from the Reaction of [Re2(CO)8(MeCN)2] and Diazocyclopentadiene

“…Compounds 2 and 3 are derived from C 5 H 4 N 2 by loss of N 2 , while the formation of compound 1 requires H-abstraction, presumably from solvent. Compounds 1 , 2 , and 3 12 were shown spectroscopically to be the same as the published compounds. The X-ray structure of 1 is known,10b but since those of the dinuclear derivatives 2 and 3 have not been reported, we determined these in this work .…”
