A highly functionalized 9,9-disubstituted (phenylethynyl)-fluorene-appended N -methyl-7-azaindole derivatives has been synthesized from various fluorene propargylic alcohols and substituted-7-azaindoles using BF 3 OEt 2 as a catalyst. The scope of the reaction was demonstrated by selecting a range of fluorene propargylic alcohols and substituting 7-azaindoles. A plausible reaction mechanism for forming title compounds via propargylic carbocation is postulated. The synthetic transformation of the products has been demonstrated by the Suzuki coupling and Click reaction. The Suzuki coupled compounds 5a - 5e were evaluated for photophysical properties such as absorption, solvatochromism, emission, and Stokes shift and found blue emissive in nature., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

A mixture DMSO-allyl bromide has been developed as a reagent for an atom economic one-pot N -allylation and aryl bromination under basic conditions. Utilizing this reagent, N -allylation-bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction mechanism have been proposed., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)
