Zusammenfassung
A systematic study of diverse halogenation reactions of the tetrahedral Mo2P2 ligand complex [{CpMo(CO)(2)}(2)(mu eta(2)eta(2)-P2)] (1) is reported. By reacting 1 with different halogenating agents, a series of complexes such as [( CpMo)(4)(mu(4)-P)(mu(3)-PI)(2)(mu-I)(I)(3)(I-3)] (2), [{CpMo(CO)(2)}(2)(mu-PBr2)(2)] (3a), [{CpMo(CO)(2)}(CpMoBr2)(mu-PBr2)(2)] (4a), [{CpMo(CO)(2)}(2)(mu-PCl2)(2)] ...

A systematic study of diverse halogenation reactions of the tetrahedral Mo2P2 ligand complex [{CpMo(CO)(2)}(2)(mu eta(2)eta(2)-P2)] (1) is reported. By reacting 1 with different halogenating agents, a series of complexes such as [( CpMo)(4)(mu(4)-P)(mu(3)-PI)(2)(mu-I)(I)(3)(I-3)] (2), [{CpMo(CO)(2)}(2)(mu-PBr2)(2)] (3a), [{CpMo(CO)(2)}(CpMoBr2)(mu-PBr2)(2)] (4a), [{CpMo(CO)(2)}(2)(mu-PCl2)(2)] (3b), and [{CpMo(CO)(2)}(CpMoCl2)(mu-PCl2)(2)] (4b) were obtained. Whereas the reaction of 1 toward various bromine and chlorine sources leads to similar results, a different behavior is observed in the reaction with iodine in which 2 is formed. The products were comprehensively characterized by spectroscopic methods and single crystal X-ray diffraction, and the electronic structures of 2, 3a, and 4a were elucidated by DFT calculations.
