- W2113249621 abstract "Unsymmetrical ketone phenylhydrazones (1)(R1≠ R2) react with PCl3, at room temperature to give predominantly one, (2), of the two possible 2,3-disubstituted indoles in good to excellent overall yield. When the R1 and R2 groups are very different (R1= Ph or Me; R2= alkyl or H) the reaction is highly regioselective leading to exclusive or prevalent formation of the corresponding 3-R1 indoles (2), whereas when R1 and R2 are very similar (R1,R2= alkyl chains) the regioselectivity is decreased and the indole having the shorter chain in the 3-position predominates, but only slightly." @default.
