Nickel(I) complexes were generated in situ from Ni (PPh3)2Cl2 using activated iron and the complexes combined with N,N′-bis(4-fluorobenzylidene) ethane-1,2-diamine (BFBED) were then used as a catalyst for the 1,4-addition reaction of arylboronic acids to α,β-unsaturated substrates. The reaction proceeded to completion and did not require the addition of a base but the addition of potassium iodide is
By improvement of the classical SOCl2-pyridine method for the preparation of acid chlorides, amides and opticallypurepeptides were synthesized rapidly in a simple manner from DCHA dicyclohexylammonium) salts of carboxylic acids. This modified SOCl2-pyridine method was applied to a rapid synthesis of TRH.
