Abstract
Substantial yield increases have been noted in the use of a di-SmI2 binding ligand for the pinacol coupling of alkyl aldehydes compared to 1:1 complex es of SmI2 and tetraglyme. High diastereoselectivities of ca. 10:1 are also observed for alpha-substituted alkyl aldehydes in favour of the (+/-)-isom ers.
