Palladium(0) and phase transfer catalyzed conversion of azirines to styrylindoles. Alper, Howard; Mahatantila, Chulangani P. (Ottawa-Carleton Inst. Grad. Stud. Chem., Univ. Ottawa, Ottawa, ON K1N 9B4, Can.). Heterocycles, 20(10), 2025 (English) 1983. 56-37-1 and 577-16-2 are also in the experiment. CODEN: HTCYAM. ISSN: 0385-5414. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) 2-Phenyl-1-azirizines I (R = H, Me, OMe; R1 = H, Me) were treated with (Ph3P4)Pd and PhCH2N+Et3 Cl- in a mixt. of NaOH and C6H6 under CO to yield indoles II and acetophenones. I (R = R1 = H) was treated with (Ph3P)4Pd and PhCH2N+Et3 Cl- in C6H6/50% NaOH under CO to give II (R = R1 = H) and PhCOMe. .
