Cyclopropane phenyl ether
WebAn 1,3-indanedione-derived donor–acceptor cyclopropane, bearing the ethoxymethyl-protected phenolic group at the ortho -position of the donor aryl substituent, has been synthesized using a reaction sequence involving the Knoevenagel condensation of 1,3-indanedione with the corresponding protected salicylaldehyde followed by the … WebCyclopropane is a cycloalkane molecule with the molecular formula C 3 H 6, consisting of three carbon atoms linked to each other to form a ring, with each carbon atom bearing two hydrogen atoms resulting in D 3 h molecular symmetry. The small size of the ring creates substantial ring strain in the structure.
