Three isostructural Mn(II) compounds with a zwitterionic dicarboxylate ligand and different pseudohalides were synthesized, and then structurally and magnetically characterized. They are formulated as [Mn(L)(X)(2)(H(2)O)(2)](n) [X = N(3)(-) (1), NCO(-) (2), NCS(-) (3), L = 1,4-bis(4-carboxylato-1-pyridinium)butane]. In these compounds, adjacent Mn(II) ions are connected into coordination chains...
The presence of a proximal cationic group in zwitterionic aryltrifluoroborates such as o-(Ph(2)MeP)C(6)H(4)(BF(3)) stabilizes these compounds against hydrolysis.
The ambiphilic phosphino-borane i-Pr2P(o-C6H4)BMes2 affords stable versions of key zwitterionic intermediates by reactions with diethyl azodicarboxylate or PhNCO.
A facile synthesis of highly functionalized 2H-iminopyran derivatives by the multi-component reaction of cyclohexyl isocyanide, dialkyl acetylenedicarboxylates, arylglyoxals and arylamines is described. The zwitterionic intermediate produced by addition of cyclohexyl isocyanide to electron-deficient acetylene diesters was trapped by the electrophilic imine moiety of α-iminoketones, derived from...
