Bifunctional copper-based photocatalyst for reductive pinacol-type couplings

A bifunctional copper-based photocatalyst has been prepared that employs a pyrazole-pyridine ligand incorporating a sulfonamide moiety that functions as an intramolecular hydrogen-bond donor for a photochemical PCET process. In typical reductive PCET processes, the photocatalyst and H-bond donor must have an appropriate redox potential and pKa, respectively, to promote the PCET. When working in concert in a bifunctional catalyst such as Cu(pypzs)(BINAP)BF4, the pKa of the H-bond donor can have an acidity that is orders of magnitude less and still efficiently promote the PCET process. A reductive pinacol-type coupling can be performed using a base-metal derived photocatalyst to afford valuable diols (24 examples, 46-99% yield), from readily available aldehydes and ketones.

Reductive coupling of carbonyl compounds to pinacols by using Sm-I2MeOH or Sm-I2-Ti(O(i)Pr)4-MeOH systems

The coupling reaction of aromatic carbonyl compounds was performed with Sm-I2 or Sm-I2-Ti(O(i)Pr)4 in methanol. Meso isomer was mainly produced in the presence of Ti(O(i)Pr4.
