By action of in THF at room temperature, aromatic carbonylcompounds produce the corresponding 1,2-diols via reductive coupling reaction and 1,1-dicyanoalkenes produce the functionalized cyclopentenes through reductive dimerization followed by intramolecular cyclization in one-pot. The former gives approximately equal amounts of (dl)- and (meso)-1,2-diols and the later gives the major trans-form products
