Cullen, Aaron J.,Sammakia, Tarek
, p. 3143 - 3145 (2004)
(Chemical Equation Presented) The conversion of 1-(2-methoxyethoxy)ethyl- protected β-hydroxy ketones to syn-1,3-ethylidene acetals is effected by Et3SiH and SnCl4. This reaction is proposed to proceed via a cyclic oxocarbenium ion i
Vinylation of hydroxy-containing cyclic formaldehyde acetals with acetylene
Oparina,Vysotskaya,Parshina,Khil'ko,Gusarova
, p. 1434 - 1437 (2008)
Nucleophilic addition of alcohols having cyclic acetal fragments to acetylene smoothly occurs under relatively mild conditions (KOH, 100-125°C, 1-2 h, initial acetylene pressure 11-12 atm) to give the corresponding vinyl ethers in 80-83% yield.
Influence of Boiling on the Radiolysis of Diglyme
Vlasov,Kholodkova,Ponomarev
, p. 312 - 318 (2018/08/01)
The radiolysis of diethylene glycol dimethyl ether (diglyme) in a boiling state has been studied for the first time. Boiling facilitates the cleavage of internal C–O bonds, weakens the cage effect and diglyme regeneration processes, and facilitates the exchange and dimerization reactions of radicals. As compared with radiolysis at room temperature, the amount of unsaturated products of diglyme fragmentation formed during irradiation in the boiling state is smaller by a factor of 4, and the disproportionation products of heavy radicals are found in negligible amounts, if any. The yield of radiolytic decomposition of diglyme under boiling conditions is ~15 molecule/100 eV, which is higher than that at room temperature by a factor of almost 1.5.

Paragraph 0054; 0055; 0056; 0057; 0058, (2017/03/21)
The present invention regards metallo-silicate materials comprising a metal ion selected from one or more of the group consisting of potassium ions, sodium ions, lithium ions, rubidium ions and caesium ions. The materials are useful preparing lactic acid and 2-hydroxy-3-butenoic acid or esters thereof from a sugar.
