✦ Synopsis

Most alkylrhenium(VI1) oxides, e.g. ((cyclo)-C3H5)Re03 (2) SOTS, fully characterized and are available in much higher are rather sensitive to temperature and moisture with the yields than their ReVr1 congeners. Mixed tetraalkyltetraoxoprominent exception of methyltrioxorhenium (1). The corres-dirhenium(V1) complexes (R # R') synthesized from 1 and ponding alkylrhenium(V1) oxides of formula [RR'(O)-dialkylzinc compounds form as a mixture of &/trans isomers. Re(p-O)], [R = R' = (cyclo)-C3H5 (3), iPr (4); R = CH3, R' = They are oily liquids at room temperature. The Re=O and CzH5 (5), R = CH3, R' = iPr (6)] are much more stable in this Re-Re stretching force constants as a measure of the bond regard. They can be handled in air at room temperature. strengths, were determined from IR and Raman data.
