General Description

BIS(DIMETHYLAMINO)DIPHENYLSILANE is a chemical compound that belongs to the category of organosilicons. Its molecular formula is C16H24N2Si. BIS(DIMETHYLAMINO)DIPHENYLSILANE is highly reactive due to the presence of two dimethylamino groups. It has a variety of applications, predominantly in the realms of chemical synthesis and semiconductor industries. Typically, it is used as a precursor in the preparation of other chemicals or as a reagent for creating specific chemical reactions. As with most organosilicons, it's important to handle it with proper safety measures due to its potential reactivity and hazardous effects.

Chloraminosilanes II. Preparation and spectroscopic studies on alkyl-(dimethylamino)chlorosilanes

Several new compounds containing both chloro and dimethylamino groups linked to silicon have been prepared. The general method involved reacting a solution of the appropriate polychlorosilane in ether at ca. - 50° with a chilled ethereal solution of dimethylamine. Prepared in this fashion were CH3Si(NMe2)Cl2, CH3Si(NMe2)2-Cl, PhSi(NMe2)Cl2, PhSi(NMe2)2Cl, CH3(H)Si(NMe2)Cl, (CH3)2Si(NMe2)Cl, CH2CH(CH3)Si(NMe2)Cl, and Ph2Si(NMe2)Cl. Comparison of the spectra of these compounds with those in the perhalo and peramine series showed that replacement of NMe2 for Cl resulted in an upfield shift of the resonances of the other groups linked to silicon, a shift which parallels that observed upon substitution of CH3 for Cl. The relationship of ν(SiH) in the IR and δ(SiH) in the NMR spectra was linear.
