Synthesis of the dimeric, N substituted μ2-O aminoalkoxy complexes of rhenium [(CO)3Re(μ2-O∩NHR)]2

The allyl rhenium complex Re(CO)4(η3-C3H5) (1) reacts with the N substituted amino alcohols 2a–f to give the N substituted dimeric μ2-O-bridged tricyclic aminoalkoxy complexes of rhenium of the type [(CO)3Re(μ2-O∩NHR)]2 (3a–f). The compounds have been characterized by spectroscopic (IR, NMR, MS), analytical (C, H, N) and X-ray diffraction techniques (3a–f).
