A series of dimethylaminosilanes of the types (C2 Hs) 4 _ nSi [N (CH3hln and RR3 _ nSi [N (CH3hln (11= 1-4, R= CHz= CH-, p-(CH3hHSiC6Hs--, Hand R'= CH3- and C2 Hs-) was prepared. The relative basicities of the nitrogen atoms in these compounds were determined by infrared spectroscopy. The~ v values of the hydrogen bonds of deuteriochloroform (pyrrole) with the dimethylaminosilanes studied are interpreted in terms of a (p->-d) n; ...
