Abstract: Abstract Recently, a crystal structure of V-nitrogenase was presented, showing that one of the ยต2 sulphide ions in the active site (S2B) is replaced by a lighter atom, suggested to be NH or NH2, i.e.… read more here.

Abstract: A novel tandem Blaise reaction for the one-pot synthesis of substituted NH-pyrroles was described. The Blaise reaction intermediate, generated in situ from Reformatsky reagent and nitrile, reacted with arylglyoxals chemoselectively to afford a wide variety… read more here.
