An iron(ii) spin-crossover metallacycle from a back-to-back bis-[dipyrazolylpyridine] [PDF]

, 2015
The syntheses of 4-mercapto-2,6-di(pyrazol-1-yl)pyridine (bppSH) and bis[2,6-di(pyrazol-1-yl)pyrid-4-yl]disulfide (bppSSbpp) are reported. In contrast to previously published “back-to-back” bis-[2,6-di(pyrazol-1-yl)pyridine] derivatives, which form ...

Reactive trityl derivatives: stabilised carbocation mass-tags for life sciences applications [PDF]

, 2008
The rational design of novel triarylmethyl (trityl)-based mass tags (MT) for mass-spectrometric (MS) applications is described. We propose a "pKR+ rule" to correlate the stability of trityl carbocations with their MS performance: trityls with higher pKR+
