Yet Another Acene Synthesis (YAAS)


Who doesn’t like a good fused benzene synthesis? Lin et al. have come up with a new iterative method to make acenes.[ChemComm] The new method uses a series of Wittig olefinations and Knoevenagel condensations, schematically shown below. The method works up to [4]acene and requires photochemical tricks to get higher order acenes, but the precursors …
