Aroylation of Electron-Rich Pyrroles under Minisci Reaction Conditions
Laha, Joydev K.,Kaur Hunjan, Mandeep,Hegde, Shalakha,Gupta, Anjali
, p. 1442 - 1447 (2020/02/22)
The development of Minisci acylation on electron-rich pyrroles under silver-free neutral conditions has been reported featuring the regioselective monoacylation of (NH)-free pyrroles. Unlike conventional Minisci conditions, the avoidance of any acid that could result in the polymerization of pyrroles was the key to success. The umpolung reactivity of the nucleophilic acyl radical, generated in situ from arylglyoxylic acid, could help explain the mechanism of product formation with electron-rich pyrroles. Alternatively, the nucleophilic substitution of the acyl radical on the electron-deficient pyrrole radical cation is proposed.

A novel method has been developed for the synthesis of 3-pyrrolines from β-ketopropargylamines via a 5-endo-dig carbocyclization. This transformation involves a silver-catalyzed Conia-ene type reaction tolerating broad substrate scope with good to excellent yields. Furthermore, this methodology has been extended for the construction of 2-substituted pyrroles under base-mediated conditions. Copyright

We herein report a novel one-pot reaction for benzoylation of pyrrole. The key step in the reaction is generation of di(1H-pyrrol-1-yl)zirconium(IV) chloride complex which reacts with benzaldehydes and methyl benzoates to give 2-benzoylpyrroles as the major product.

Page/Page column 36, (2008/06/13)
The present invention provides novel ketopyrroles having structure XXIV wherein R2 is independently at each occurrence a deuterium atom, a halogen, a nitro group, an amino group, a C3-C40 aromatic radical, a C1-C50 aliphatic radical, or a C3-C40 cyclcoaliphatic radical; “a” is an integer from 0 to 3; and X1 and X2 are independently at each occurrence a bromine atom, a hydroxy group, or the group OR10, and wherein the group R10 is independently at each occurrence a deuterium atom, a halogen, a nitro group, an amino group, a C3-C40 aromatic radical, a C1-C50 aliphatic radical, or a C3-C40 cyclcoaliphatic radical. Ketopyrroles XXIV are useful ligands for the preparation of Type (1) and Type (2) organic iridium compositions. In one aspect, the present invention provides deuterated analogs of XXIV. Organic iridium compositions are useful in the preparation optoelectronic devices, such as OLED devices and photovoltaic devices exhibiting enhanced performance characteristics.
