WebOct 1, 2013 · Seven cis-tetracarbonylmolybdenum complexes of RP(OR′O) phosphonite ligands (R = phenyl, 2-thienyl; ORO = 1,1′-bi-2-naphthoxy, 4-tert-butylphenoxy, and catechoxy) have been synthesized and characterized by multinuclear NMR spectroscopy and X-ray crystallography.These studies indicate that the electron-donor abilities depend on the R … WebStaudinger ReactionStaudinger Reduction. Azides may be converted to amines by hydrogenation, but another possibility is the Staudinger Reaction, which is a very mild azide reduction. As there are a variety of methods for preparing azides readily, the Staudinger Reaction makes it possible to use - N 3 as an - NH 2 synthon. reaching definitions in compiler design
