Abstract
Under solvent-free conditions and at 80 °C, a DMAP- or imidazole-mediated clean and rapid conversion of cyclic Morita-Baylis-Hillman (MBH) acetates into the corresponding γ-keto allyl phosphonates in 70-93% yields is described herein. This allylic nucleophilic substitution works well with primary and secondary acetates bearing, at the β'-position, linear or branched alkyl groups and aryl groups.

MAGNETIC RESONANCE IN CHEMISTRY : MRC 2015; 53:952-970.

Abstract
Standard 2D NMR experiments suffer from the many t1 increments needed for spectra with sufficient digital resolution in the indirect dimension. Despite the different methodological approaches to overcome this problem, these increments have prevented studies of fast reactions. The development of ultrafast NMR (UF-NMR) has decisively speeded up the time scale of standard NMR to allow the study of organic reactions as they happen in real time to reveal mechanistic details. This mini-review summarizes the results achieved in monitoring organic reactions through this exciting technique.
