Preparation of enol ethers by carbonyl olefination utilizing an alkoxymethyl chloride–titanocene(II) system
摘要:
Aldehydes, ketones, esters and lactones are transformed into enol ethers or 1,2-dialkoxy-l-alkenes by treatment with organotitanium species prepared from alkoxymethyl chlorides and a titanocene(II) complex. (C) 2003 Elsevier Ltd. All rights reserved.

(Alkoxymethyl)dodecyldimethylammonium, (cycloalkoxymethyl)dodecyidimethylammonium, (alkylthiomethyl)dodecyldimethylammonium, (alkoxymethyl)dimethyloctylammonium, (cycloalkoxymethyl)dimethyloctylammonium and (alkylthiomethyl)dimethyloctylammonium chlorides were prepared in high yield. All the chlorides studied showed antimicrobial activity. The relationship between the chemical structure and antimicrobial activity was analyzed using the rough sets method.
