2 NMR Spectra in Toluene-d8 Zn alkoxide solutions in non-polar solvents have a tendency to precipitate that is alleviated by the addition of excess alkylzinc reagent in the pyrimidine case. The general features of the NMR spectra in thf-d8 are reproduced in C7 D8 . 01 ppm signals observed in thf-d8 . DFT calculations indicate the stability of a doubly thf-solvated structure with additional O – Zn bonding. 5 ppm region, corresponding to the homo- and heterochiral forms (48 : 52). On increasing the temperature these broaden and then coalesce at 348 K (Fig.

A conventional catalytic reaction would demonstrate only constant heat output (zero order in reactants) or decay over time (finite order in reactants). The first experiments carried out by Blackmond and Brown employing this technique are shown in Fig. 6 [73]. They demonstrate autocatalytic behavior as expected, and much can be learned about the reaction by analysis of the heat output from scalemic, racemic and enantiopure alcohols in separate experiments. The characteristic shapes permit testing against numerical integration of various model mechanisms.

In all probability the triggers were in place prior to the existence of pre-cellular structures, and thus involved purely chemical events. In the absence of experiment, or any real prospect thereof, there has been intense speculation about how prebiotic “symmetry-breaking” might have occurred [1–4]. This speculation has centred on physical mechanisms (parity violation, photolysis with plane polarised light, chirality enhancement through amplifying crystallisation processes, selective homochiral polymerisation) that have been presented by several reviewers, generally without a specific conviction to adopt one explanation over another [5–12].
