Synthesis of second generation ATH catalysts

1 Synthesis of phosphonium dimers protected phosphine aldehydes 

Our group developed a convenient multi-component template synthesis for iron complexes with ligands that form five-membered M-P-N- metallacycles. It has been used to make P-N-N, P-N-S, P-N-P mono- and bis-tridentate iron complexes,
