New Addition Reactions. IV. The Addition of Schiff Bases to Diketene

Addition to the knowledge of the genus Agaricus in Iran

Five taxa viz, Agaricus altipes, A. cupreobrunneus, A. placomyces, A. porphyrocephalus, and A. urinascens var. urinascens are reported as new records for Iran. Details of taxonomical important features are also presented herewith. New localities in the west and north-west of the country are reported as habitats of Agaricus speciesin Iran.  

Conjugate addition–enantioselective protonation reactions

The addition of nucleophiles to electron-deficient alkenes represents one of the more general and commonly used strategies for the convergent assembly of more complex structures from simple precursors. In this review the addition of diverse protic and organometallic nucleophiles to electron-deficient alkenes followed by enantioselective protonation is summarized. Reactions are first categorized...

Cooperative bimetallic oxidative addition reactions*

The factors that control the oxidation of metals in bimetallic complexes are investigated in relation to the possibility of developing one-site addition two-metal oxidation reactions such as those that occur in the respiratory protein, hemerythrin. It is shown that the behavior of bimetallic complexes is not represented by the sum of the analogous monometallic parts because of metal and ligand ...

The New Addition

Design and synthesis of new symmetrical Schiff bases

A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.
