The fluxional molecule Os3(CO)7[P(OMe)3]5 has been prepared from OS3(CO)12 and P(OMe)3 by a combination of thermal and UV irradiation synthetic methods. An investigation by 31P and 13C NMR spectroscopy indicated that the mechanism of fluxionality in this compound probably involves the P(OMe)3 ligand of the Os(CO)3[P(OMe)3] unit moving from one equatorial site to the other via a trigonal twist mechanism
通过OS 3(CO)12和P(OMe)3的结合,通过热和紫外线辐照合成方法制备了通量分子OS 3(CO)7 [P(OMe)3 ] 5。通过31 P和13 C NMR光谱进行的研究表明,该化合物的通量性机理可能涉及OS(CO)3 [P(OMe)3 ]单元的P(OMe)3
