Organic & Biomolecular Chemistry, 1(22), 4025-4029 (English) 2003 Royal Society of Chemistry. CODEN: OBCRAK. ISSN: 1477-0520. 1003-31-2 and 10025-82-8 which are cas registry numbers are also used here. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Gallium(III) and indium(III) halides were found to mediate the condensation of cyclopropenes and nitriles to give pyrroles, e.g., I, in moderate yields. When excess nitrile was present, diazepine II was also formed. .

Synthesis of 2,2'-bipyrroles and 2,2'-thienylpyrroles from donor-acceptor cyclopropanes and 2-cyanoheteroles: Synthesis of 2,2'-bipyrroles and 2,2'-thienylpyrroles from donor-acceptor cyclopropanes and 2-cyanoheteroles.Several substances are used for example 1003-31-2 which is its cas registry number.

Organic Letters, 6(6), 1057-1059 (English) 2004 American Chemical Society. 1003-31-2 are also occured in this study. CODEN: ORLEF7. ISSN: 1523-7060. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Two series of 2,2'-bipyrroles, e.g., I (X = NH), and 2,2'-thienylpyrroles, e.g., I (X = S), have been prepd. by trimethylsilyl trifluoromethanesulfonate-mediated reaction of donor-acceptor cyclopropanes, e.g., II, with 2-cyanopyrroles and 2-cyanothiophene, resp. This method opened the door for synthesis of a wide variety of unsym. bipyrroles and thienylpyrroles. ..
