Formation of two isomeric closo-[(eta(5)-C5H5)FePC2B8H10] phosphadicarbaborane analogues of ferrocene via isolable eta(1)-bonded complexes of the [7-{(eta(5)-C5H5)Fe(CO)(2)}-(eta(1)-nido-PC2B8H10)] type.
Original language description
The reaction of nido-[7,8,9-PC2B8H11] (1) with [{CpFe(CO)(2)}(2)] (Cp = eta(5)-C5H5-) in benzene (reflux, 3 days) gave an eta(1)-bonded complex [7-Fp-(eta(1)-nido-7,8,9,-PC2B8H10)] (2; Fp = CpFe(CO)(2); yield 38%). A similar reaction at elevated temperatures (xylene, reflux 24 h) gave the isomeric complex [7-Fp-(eta'-nido-7,9,10-PC2B8H10)] (3; yield 28 %) together with the fully sandwiched complexes [1-Cp-closo-1,2,4,5-FePC2B8H10] 4a (yield 30%) and [1-Cp-closo-1,2,4,8-FePC2B8H10] 4b (yield 5%). Compounds 2 and 3 are isolable intermediates along the full eta(5)-complexation pathway of the phosphadicarbaborane cage; their heating (xylene, reflux, 24 h) leads finally to the isolation of compounds 4a (yields 46 and 52%, respectively) and 4b (yields 4 and5%, respectively). Moreover, compound 3 is isolated as a side product from the heating of 2 (yield 10%). The structure of compound 4a was determined by an X-ray structural analysis and the constitution of all compounds is consistent with
