Properties and Reactions of Organosilanes and Organogermanes Containing the Potentially Bidentate (X(CH2)n)2N-Group
Abstract
Compounds in the series R SiN[(CH ) X] (R = (CH ) H, (CH ) Cl, and CH ClH), R Si[N((CH ) X) ] (R = (CH ) , C H H, and C H Cl), R GeN(CH X) (R = (CH ) Cl and (C H ) Cl), and Cl Sn[N-((CH ) X) ] , for X = N(CH ) , n = 3; and OCH , n = 2, have been prepared and characterized by H, C and Si NMR spectroscopy, and by elemental analyses. For all the compounds studied, the terminal N(CH ) and OCH groups appear not to coordinate to the central atom. The product C H Si{N[(CH ) OCH ] } B[3,5-(CF3)2C6H3]4, obtained from a reaction between C H HSi{N[(CH ) OCH ] } and (C H ) CB[3,5- (CF ) C H ] , should contain a silylium ion, but because of the suspected presence of a small quantity of silyl radical, has thus far eluded definitive characterization. 3 2 n 2 3 2 3 2 3 2 2 n 2 2 3 2 6 5 6 5 3 2 2 3 2 6 5 2 2 2 3 2 2 3 2 3 3 2 3 6 5 2 2 3 2 2 6 5 2 2 3 2 2 6 5 3 3 2 6 3 4 1 13 29
