  A sequential benzoin/Michael/acetalization tandem reaction catalyzed by NHC and amine together has been developed to assemble aromatic aldehydes and enals into chiral tetrahydrofuran derivatives bearing multiple functional groups and stereogenic centers with high stereoselectivity of up to 95:5 dr and 96% ee. The high yield and stereocontrol of this process may be due to both acid‐promoted symmetrization

  atoms at the 2-position in the benzene rings of bis(1,2-diaryl-1,2-ethylenedithiolato)nickel caused a pronounced hypsochromic shift of the absorption band in near-infrared region and improved the solubility to benzene. The nickel complexes with 2-halogen atoms are effective quenchers of singlet oxygen.
