Resulting in Enantiopure Structures at Metal Surfaces

3 Induction of Chirality by Enantiopure Chiral Molecules in 3D, Resulting in Enantiopure Structures at Metal Surfaces 

So far we have examined situations in which the adsorbed molecule has chirality in 2D, but we will now look at the organization of chiral molecules in 3D at a metal surface. We will examine three cases concerned with axial chirality or chirality centred on carbon. 

Raval and Ernst have particularly studied the adsorption of tartaric acid at the surface of Cu (110) and Ni (110). Knowing the role that tartaric acid (6.4)-2H plays in the enantioselective catalytic hydrogenation of -ketoesters by as well as 

On a Ni (110) surface at ambient temperature, double deprotonation of the (R, R)- [(6.4)-2H ] occurs to form the ditartrate anion (6.4), which is strongly adsorbed at the metal surface.The results of scanning tunnelling microscopy (STM) reveal the formation of a 

On a Cu (110) surface, the behaviour of tartaric acid is different. The interactions of the TA dianion with the surface, which are dominant in the case of Ni
