Abstract
In the absence of added reducing agent PMe3 reacts with the dimers (I) in a sequential manner leading via the isolable intermediates (V) and (VI) to the new electron-rich nitrosyl complexes (III).
ChemInform Abstract
In the absence of added reducing agent PMe3 reacts with the dimers (I) in a sequential manner leading via the isolable intermediates (V) and (VI) to the new electron-rich nitrosyl complexes (III). From a practical point of view the most convenient synthesis of (III) is the direct treatment of (I) with an excess of (II) in a reaction time of 3 h for M: Mo and of 5 d for M: W. In the presence of areducing reagent the reaction of (I) and (II) affords the related compounds (VII) which also contain electron-rich transition metal centers.
