A new method for the synthesis of the indolocarbazole alkaloid arcyriaflavin A is described. The synthetic strategy employs a graphite-catalysed alkenation, one-pot oxidation-Wittig reaction, iodine-catalysed electrocyclisation ...

We argue that (trans)-4-chloro-4'-nitrostilbene is not a new organic nonlinear optical material as claimed by Dinakaran and Kalainathan [P.M. Dinakaran, S. Kalainathan, Synthesis, growth, structural, spectral, thermal, ...

It is argued that the nonlinear optical single crystal `l-asparagine cadmium chloride monohydrate' grown by the slow evaporation solution growth technique by Masilamani et al. (Optik, 123 (2012) 1304-1306) is actually the ...

Reinvestigation of the growth of thiosemicarbazide potassium chloride crystal (1) (Chandrasekaran et al. [1]) and thiosemicarbazide lithium chloride crystal (2) (Maadeswaran et al. [2]), unambiguously confirms that compounds ...

Slow evaporation of an aqueous solution containing l-threonine and magnesium sulphate heptahydrate, results in the fractional crystallization of the less soluble l-threonine crystal and not any novel optoelectronic 'magnesium ...
