ANODIC FUNCTIONALIZATION OF OLEFINS IN ALCOHOLS IN THE PRESENCE OF HALIDE SALTS
Elinson, M. N.,Makhova, I. V.,Nikishin, G. I.
, p. 112 - 118 (2007/10/02)
Electrolysis of conjugated, unbranched arylolefins in the presence of alkali metal halides in alcohols affords 1-aryl-2-bromoketals in 60-90percent yields.Under these conditions, 2-methyl-1-phenylprop-1-ene is converted into 1-bromo-2-methyl-1-phenylprop-1-ene in 80percent yield, and arylolefins with no benzylidene hydrogens give 1-aryl-1-alkoxy-2-bromoalkanes.
Reactions of 1-(α-Alkoxyalkyl)- and 1-(α-(Aryloxy)alkyl)benzotriazoles with the Grignard Reagents. A New and Versatile Method for the Preparation of Ethers

1-(α-Alkoxyalkyl)benzotriazoles deriving from aldehydes (other than formaldehyde), or from ketones, react with Grignard reagents at 110 deg C to provide a high-yielding, general synthesis of dialkyl and aryl ethers.Under similar conditions, 1-(alkoxymethyl)- and 1-((aryloxy)methyl)benzotriazoles give, by a different cleavage pattern of the N-C-O grouping, 1-alkylbenzotriazoles and N,N'-dialkyl-o-phenylenediamines.The 1-(α-alkoxyalkyl)benzotriazoles are easily prepared: (a) by condensation of benzotriazole, an aldehyde, and an alcohol under water-removing conditions; (b) by condensation of a 1-(α-chloroalkyl)benzotriazole with a sodium or potassium alkoxide or aryloxide; and (c) by condensatioon of an acetal or a ketal with benzotriazole.All the 1-(α-alkoxyalkyl)benzotriazoles and dialkyl or alkyl aryl ethers obtained were fully characterized by their 1H and 13C NMR spectra.
Some Methoxysilanes, Disiloxanes and Digermoxanes with Effectiveness of Odour. Sila-Substituted Perfumes, III.

The odour of the formerly unknown compounds benzyldimethylmethoxysilane 2a (flower-honey like with a minty component; intensity middle), bis(benzyl)tetramethyldisiloxane 4a (flowerlike; very weak) and bis(benzyl)tetramethyldigermoxane 9 (almond-soapy like; relatively strong) was registered and compared with related compounds (for example benzyldimethylmethoxymethane 5a, camphor-radish like).Information is given on preparation and analytical and structural investigation of several methoxysilanes and disioxanes with benzyl and phenethyl groups (compare equations and experimental part). - Keywords: Digermoxanes; Disiloxanes; Methoxysilanes; Odour; Sila-perfumes
