Synthesis and structure determination of stereoisomeric 2,2’-dibenzoyl-3,3’,4,4’-tetramethyl-1,1’-diphosphaferrocenes
; Małecka, Magdalena
; (ARKAT USA, 2007)
Reaction of 3,3’,4,4’-tetramethyl-1,1’-diphosphaferrocene 1 with an excess of benzoyl chloride and AlCl3 afforded a ~1:1 mixture of meso- and rac-2,2’-dibenzoyl-3,3’,4,4’-tetramethyl-1,1’- diphosphaferrocenes 2, which ... -
Temperature-dependent polymorphism of N-(4-fluorophenyl)-1,5-dimethyl-1H-imidazole-4-carboxamide 3-oxide: experimental and theoretical studies on intermolecular interactions in the crystal state
(Springer US, 2014)X-ray analysis of N-(4-fluorophenyl)-1,5-dimethyl-1H-imidazole-4-carboxamide 3-oxide reveals the temperature-dependent polymorphism associated with the crystallographic symmetry conversion. The observed crystal structure ...
