Ring Opening Alkylation of Tetrahydrofuran with Some Heterosubstituted Organolithium Reagents by the Aid of Boron Trifluoride Etherate
Imai, Toshiro,Muramoto, Tomoki,Tsuji, Takashi
, p. 355 - 356 (1995)
Organolithium reagents stabilized by halogeno, thio, silyl, vinyl and/or phenyl substituent(s) can cleave THF effectively under the influence of boron trifluoride etherate at lower temperatures.The softness of these carbanionic reagents seems to be import
Catalyst-dependent selective synthesis of O/S- and S/S-acetals from enol ethers
Braga,Silveira,Dornelles,Zeni,Galarza,Wessjohann
, p. 3155 - 3162 (2007/10/02)
Enol ethers are reacted with mercaptanes to give the corresponding O/S- or S/S-acetals in medium to high yield. Either product can be formed selectively depending on the acid catalyst and the reaction time applied.
MONOTHIOACETALIZATION OF ACETALS USING DIETHYLALUMINIUM THIOPHENOXIDE
Masaki, Yukio,Serizawa, Yuzuru,Kaji, Kenji
, p. 1933 - 1936 (2007/10/02)
Reactions of diethylaluminium thiophenoxide (Et2AlSPh) with acetals of several types, in which acyclic, cyclic, and bicyclic ones are involved, were examined in comparison with the known reaction using thiophenol in the presence of Lewis acid and found to provide a new and efficient method for preparation of monothioacetals.
