APPROACHES TO THE GENERATION OF 2,3-INDOLYNE
Conway, Samuel C.,Gribble, Gordon W.
, p. 2095 - 2108 (2007/10/02)
Several unsuccessful attempts to generate and trap 1-phenylsulfonyl2,3-indolyne (4) from lithio-3-bromo-1-phenylsulfonylindole (9) and 2-lithio-3-iodo-1-phenylsulfonylindole (12), generated by different methods, are described.The remarkable stability of 9
