Organomagnesium structures synthesized

TABLE 2. Structurally characterized organomagnesium amides synthesized from the reaction of metal amides with Grignard reagents... 

The stability of synthesized organomagnesium structures depends on atomic metal content Xat— that is, Nm/Nm + Np, where Nm and N are the amount of metal atoms and polymer chain units, respectively. At high Xat of Mg (>40... 

The hydrosilane reagents used, where available, were obtained from commercial suppliers such as Pierce Chemical (Rockford, 111.), Peninsular Chem Research (Gainesville, Fla.), and Matheson, Coleman and Bell (Norwood, Ohio). Others were synthesized by the lithium aluminum hydride or deuteride (Alfa Chemical, Beverly, Mass.) reduction of appropriate organic chloro- or fluorosilane, either purchased from the above-mentioned sources or synthesized by conventional routes involving organomagnesium or -lithium condensations with halosilanes. All such compounds were at least 98% pure as determined by vapor-phase chromatography (VPC). Structural identity was established by molecular analysis, infrared, and NMR spectroscopy where necessary.
