Bis[indanyl]- and bis[indenyl]arylmethanes: New molecular three-bladed propellers
摘要:
Proton-catalyzed arylmethylation of indan and indene derivatives with 4-methoxybenzaldehyde yield novel triarylmethanes bearing indan or indene substituents. According to Mislow's definition, these molecules belong to the class of molecular three-bladed propellers and exhibit an interesting stereochemistry.
