Electronically deactivated and/or sterically hindered substrates undergo the Newman-Kwart rearrangement (NKR) at around 300°C using modern microwave technology. In addition, several previously reported difficult examples were re-investigated, and the NKR under the reported conditions was found to be a reliable and high yielding reaction.

Microwave technology has proven to be ideal for investigating the Newman-Kwart rearrangement (NKR) at high temperatures and facilitated the confirmation of many aspects of this valuable reaction. Comparisons between thermal and microwave results indicate no evidence of a significant microwave effect.
