Web4 de fev. de 2015 · You cannot have a chiral carbon that doesn't have 4 groups attached to it (i.e. must be sp3 hybridized). If you think you've found a chiral carbon that only has 3 groups attached to it, you're probably forgetting the unwritten hydrogen. In this example specifically, there is only one chiral carbon, the one attached to the secondary alcohol. WebThese obstacles could potentially be resolved via the use of nickel catalysis in combination with judiciously designed chiral NHC ligands, such as the more elusive chiral CAAC-type or mesoionic NHC ligands that have found limited applications to date. 150 Another exciting prospect in this field could be the integration of NHCs as ligands for nickel/photoredox … ctv news edmonton streaming
