A high yielding three-component reaction between β-iodo ethylamine derivatives, MeOH and gaseous CO2 at ambient temperatures and pressures is reported using silver(i) oxide. Unfunctionalised alkyl iodides were also found to be effective in this transformation and their optimisation is also described. To highlight the ease and control with which gaseous CO 2 can be captured and functionalised under mild conditions, the reaction was performed using 13C-enriched CO2 to afford specifically 13C-carbonyl-labelled dialkyl carbonates with exquisite control of the isotopic purity in good yields and without the need for specialised equipment.

A range of methyl and ethyl ethers of aliphatic alcohols have been synthesized cleanly in high yield by reacting the corresponding alcohol with dimethyl carbonate or diethyl carbonate over the solid acid catalyst, I-alumina. The reaction could be conducted at ambient pressure without the need for the large excess of dialkyl carbonate as previously reported in the literature. If the reaction was conducted at high pressure, the conversion of the starting alcohol was greatly reduced. However, high pressure CO2 can be used as the solvent without significant reduction in yield. This has implications for tandem reactions.
Correlation of the rates of solvolysis of n-octyl fluoroformate and a comparison with n-octyl chloroformate solvolysis
Kevill, Dennis N.,D'Souza, Malcolm J.
, p. 240 - 243 (2007/10/03)
The specific rates of solvolysis of n-octyl fluoroformate have been measured at 24.2°C in 28 pure and binary solvents. For the 23 solvents for which both NT(solvent nucleophilicity) and YCl (solvent ionizing power) values are known, a correlation using the two-term Grunwald-Winstein equation leads to sensitivities towards changes in the two scales of 1.80 ± 0.13 (l value) and 0.79 ± 0.06 (m value), respectively. For seven solvents, a parallel study was made of n-octyl chloroformate solvolysis and F:Cl specific rate ratios were, in most instances, above unity, consistent with the association step of an association-dissociation (addition-elimination) pathway being rate-determining.
