Atmospheric Chemistry of 2-Methoxypropene and 2-Ethoxypropene: Kinetics and Mechanism Study of Reactions with Ozone

open access: yesAtmosphere, 2018
Rate coefficients at ambient temperature and atmospheric pressure for the reaction of ozone with 2-methoxypropene (2-MPE) and 2-ethoxypropene (2-EPE) were determined in an evacuable 100 L Teflon reaction chamber using absolute and relative rate methods ...

Mass spectrometry of alditols as trimethylsilyl derivatives [PDF]

open access: yes, 1969
Trimethylsilyl ethers of alditols with 3, 4, 5 and 6 C atoms were investigated. The mass spectra are unusually clearly correlated with the structures.

Addition of Chloromethyl Methyl Ether to Isoprene and the Prepation of Isogeranyl Methyl Ether

open access: yesJournal of Japan Oil Chemists' Society, 1975
The cationic addition of chloromethyl methyl ether to isoprene in the presence of metal halides was investigated in order to obtain the 1, 4-adduct, 1-chloro-3-methyl-5-methoxypentene-2. It was found that the addition of small amounts of ethyl alcohol caused a large increase in the yield of the adduct, especially in the case of stannic chloride ...

A facile route to a novel aza-crown ether incorporating three thiophene moieties [PDF]

open access: yes, 2000
The preparation of the first of a novel type of large thiophene-containing aza-crown ether is reported. The macrocycle is synthesised by linking a 3,4-dialkoxythiophene moiety with two 3-hydroxythiophene units and ring closure is effected by reaction ...

Bile acids. OV. 2,2-Dimethoxypropane: an esterifying agent preferred to diazomethane for chenodeoxycholic acid.

open access: yesJournal of Lipid Research, 1978
Artifacts formed by methylation of chenodeoxycholic acid with diazomethane are identical to the synthetic 3alpha- and 7 alpha-monomethyl ethers of methyl chenodeoxycholate. The extent of formation of these artifacts with time has been studied.
