Dual behavior of alcohols in iodine

Typical experimental procedure: To a stirred mixture of alcohol (1 mmol) and acid (3 mmol) I 2 (0 03 mmol) was added The reaction mixture was stirred at an appropriate temperature (reaction temperature 55 C or 85 C) until TLC showed complete or at least high conversion of the starting material

Direct Condensation of Carboxylic Acids with Alcohols

In order to promote atom efficiency in synthesis and to avoid the generation of environmental waste the use of stoichiometric amounts of condensing reagents or excess substrates should be avoided In esterification excesses of either carboxylic acids or alcohols are normally needed We show that the direct condensation of equimolar amounts of carboxylic acids and alcohols can be achieved

Carboxylic Acids Reactivity with Alcohols and Clustering

The rotational spectrum of the 1:1 complex formic acid–isopropylformate (FA-IPF) has been first observed when trying to assign the pulsed jet Fourier transform microwave (FTMW) spectrum of the adduct formic acid–2-propanol by expanding a binary mixture of HCOOH and 2-propanol in He The strong FTMW spectrum of isopropylformate formed by the esterification reaction was observed instead

Influence of alkyl chain length on sulfated zirconia

Esterification over the most active 0 24 mmol g −1 bulk SZ and 0 29 mmol g −1 SZ/SBA-15 materials was inversely proportional to the alkyl chain length of alcohol and acid reactants being most sensitive to changes from methanol to ethanol and acetic to hexanoic acids respectively Kinetic analyses reveal that these alkyl chain dependencies are in excellent accord with the Taft

$begingroup$ G M I haven't yet understood how the presence of more no of carbon atoms in tertiary alcohols make them more reactive than primary What I thought was if tertiary is more reactive than primary alcohol it means that carbon oxygen bond is weaker in tertiary alcohol than in primary which is making the -OH bond in tertiary alcohol to break easily than in primary when a
