The insertion reaction is determined by the strong C-nucleophilicity and S-electrophilicity of sulfene and is clearly illustrated by the primary formation of trans-[(C 6H 5) 3P(CO) 4MnS(O) 2CH 3] which isomerizes into the cis-isomer during crystallization. All compounds are well ...
Dünnschicht-Chromatographie cis-trans isomerer carbonsäurenSummary The thin-layer chromatographic behaviour of flavonoids as a function of their constitution corresponds fundamentally to the behaviour of the phenols. Analytical conditions for the separation of various flavenoids are described. ...
