  2-Ethoxyvinyllithiums and diethoxyvinyllithiums : what makes them stable or fragile?

  摘要：

  The elusive (E)-2-ethoxyvinyllithium can be readily generated in tetrahydrofuran at -75 degrees C from (E)-1-bromo-2-ethoxyethylene by halogen/metal exchange and subsequently trapped with electrophiles. Alkylation opens a convenient entry to (E)-configurated enethers. (E)-2-Ethoxyvinyllithium decomposes rapidly at -50 degrees C whereas its (Z)-isomer, which lacks the possibility to eliminate lithium ethoxide in a favorable anti-periplanar process, is stable under the same conditions. (E)-1,2-Diethoxyvinyllithium even sustains reflux temperatures (approximately 75 degrees C). 2,2-Diethoxyvinyllithium and (Z)-1,2-diethoxyvinyllithium can be conserved at 0 degrees C although this time loss of alcoholate can occur in the anti-mode. Obviously it matters whether the energy-rich ethoxyacetylene is formed as the elimination product or simple acetylene, as in the case of (E)-2-ethoxyvinyllithium. (C) 1997, Elsevier Science Ltd.

  2-functionalised vinylstannanes (E)/(Z)-Ph3SnCR′CHYRn with acetic and chloroacetic acid in CDCl3 proceeded by protodestannylation yielding Ph3SnOOCCH2X (X=H, Cl) and CHR′CHYRn. The results of kinetics measurements reveal that Lewis-basic substituents YRn facilitate the electrophilic cleavage of SnC bonds, and this effect increases with the basicity of the heteroatom Y, i.e. in the order S

  Described are synthetically produced substantially pure enol ether compositions which are cis and/or trans isomers of enol ethers having the structures: 1 wherein R 1 is C 4 -C 10 straight chain alkyl or C 9 8-alkenyl; and wherein R 2 is C 1 -C 4 alkyl, C 3 -C 4 2-alkenyl, C 4 3-alkenyl or C 10 non-allenic alkadienyl and uses thereof in imparting, augmenting or enhancing the aroma and/or taste of a consumable material such as a perfume composition, a cologne, a perfumed article such as a soap, cosmetic, hair preparation or detergent, a foodstuff, a chewing gum or an alcoholic or non-alcoholic beverage such as a carbonated beverage or fruit liquer. Also described is a process for synthesis of such enol ethers by means of (i) first forming an acetal having the structure: R 1 —CH 2 —CH(OR 2 ) 2 (ii) then carrying out a thermal decomposition reaction at pH<7 and then (iii) fractionally distilling the resulting reaction product to provide the enol ether.
