Highly stereospecific on-surface dimerization into bishelicenes: Topochemical Ullmann coupling of bromohelicene on Au(111)
Original language description
The on-surface dimerization into bis(hexahelicene) on a gold(111) surface has been studied by means of scanning tunneling microscopy and time-of-flight secondary mass spectrometry. C!C Ullmann coupling of (rac)-2-bromohexahelicene leads to formation of the (M,M)- and (P,P)- diastereomers of 2,2’-bis(hexahelicene), whilst formation of the (M,P)-diastereomer is not observed. Upon cooling, the bis(hexahelicene) aggregates into an ordered two-dimensional lattice with partly randomly distributed enantiomers. The highly specific diastereomeric coupling is explained by the surface alignment of educt in combination with the strong steric overcrowding in a possible surface-confined (M,P)-product.n
