For further evaluating the one-pot chlorination/oxidation/Wittig olefination sequence, we decided to conduct the one-pot sequential chlorination/oxidation/Wittig olefination reaction under ultrasound conditions, using MnO2 as a selective, cost-effective, and environment-friendly oxidant agent for activated alcohols 1, such as allylic alcohol, propargylic alcoho, and benzylic alcohols, to give (Z)-a-chloro-a,b-unsaturated esters 3, Scheme 1.
The high number of allylic hydrogens and double bonds per molecule associated with these unsaturated poly(vinyl ether)s results in relatively fast curing by autoxidation due to the gel-point being reached at relatively low extents of reaction.

For example, in the addition of HBr to buta-1,3-diene, as shown in Scheme III, the resultant mixture of 3-bromobut-1-ene and 1-bromobut-2-ene may be thought of as arising from the addition of Br--to different allylic carbocation resonance forms.
Despite being a rapidly cross-linking polymer, the large amount of allylic hydrogens present in NR also leads to rapid crosslink breakdown when exposed to elevated temperatures for long periods (ref.
