A new metal-free protocol is described for the synthesis of terminal acetals by tandem oxidative rearrangement of olefins using oxone as an oxidant in the presence of iodine. Moreover, a one-pot procedure for the preparation of glycol mono esters from olefins is also presented for the first time using the same reagent system.
A one-step protocol is described for the synthesis of arylacetaldehydes from aryl aldehydes or diaryl ketones by using the system of DMSO/KOH/zinc. In this transformation, DMSO provides a methine fragment that converts the −CHO structure in aryl aldehydes or the −CO− structure in diaryl ketones to the −CH2CHO structure in arylacetaldehydes via a one-carbon extension. This protocol could also be used
