Abstract

Synthesis, Crystal Structures and Electrochemistry of Ferrocenyl-Substituted 1,3,4-Oxadiazoles. -The solid-state structures of (III), (V), and (VI) are determined by X-ray diffraction and the redox behavior of oxadiazoles (III) and (VI) is studied by cyclic voltammetry, differential pulse voltammetry and by voltammetry at a rotating disc electrode. The results are discussed. -(TAUCHMAN, J.; TRNKA, J.; CISAROVA, I.; STEPNICKA*, P.; Collect. Czech. Chem. Commun. 75 (2010) 10, 1023-1040, http://dx.doi.org/10.1135/cccc2010064 ; Dep. Inorg.

New 1,1’-Ferrocene Bis(sulfonyl) Reagents

“…An alternative method for the formation of amide bonds is to use hydroxybenzotriazole, HOBt, as the leaving group . This unit has been successfully used for the activation of carbonyl functionalized ferrocenes for the formation of amino acid conjugates .…”

trans-Spanning ferrocene amidodiphosphine ligand: Synthesis, palladium complexes and catalytic use in Suzuki–Miyaura cross-coupling

“…Such donors are highly structurally versatile and potentially multidentate, thus markedly widening the spectrum of accessible ferrocene phosphinocarboxamides as well as their application field, particularly towards coordination chemistry and catalysis. Validity of this approach has been already demonstrated by the synthesis of ferrocene phosphinocarboxamides from pyridyl-substituted [7a,d] and 2-hydroxyethyl amines [10], and from amino acid esters [11].…”

Pd‐Catalyzed Enantiodivergent and Regiospecific phospha‐Michael Addition of Diphenylphosphine to 4‐oxo‐Enamides: Efficient Access to Chiral Phosphinocarboxamides and Their Analogues

“…Chiral phosphinocarboxamides have emerged to be a highly versatile class of hemilabile ligands, which have assisted in numerous metal‐mediated reactions 6. 7 In addition, they also serve as organocatalysts,8 and they are of tremendous value in biomedicine 4. 9 Similarly, phosphinocarboxylic acids are of comparable significance as they serve as chelating ligands in the economically important Shell higher olefin process 10…”
