Abstract Previously unknown N, N-bis [ethoxy (methyl) silylmethyl] amines MeN [CH 2 SiMe m (OEt) 3-m] 2 (m= 0-2) were synthesized. According to UV spectral data, only MeN [CH 2 SiMe 2 (OEt)] 2 form hydrogen bond with phenol in a heptane solution. The amines with m= 0 and 1 fail to forms hydrogen bond with phenol [under the same conditions, N- (triethoxysilylmethyl) dimethylamine Me 2 NCH 2 Si (OEt) 3 forms a strong hydrogen bond ...
