Abstract
THESIS 10884We have developed a highly efficient, broad scope, additive-free mild protocol for the oxidative carbene-catalysed esterification of aldehydes. We have unambiguously identified benzoin as the oxidised species in these aerobic NHC-catalysed aldehyde esterifications proving that these reactions are mechanistically distinct from previously reported, similar esterifications. We also reported the first carbene-catalysed aerobic oxidative cleavage of cyclic 1,2-diketones and consequently exploited this novel organocatalytic process using similar reaction conditions to allow for the one-pot synthesis of an anhydride
