A Second-Generation Janus Scorpionate Ligand: Controlling Coordination Modes in Iron(II) Complexes by Steric Modulation [PDF]

, 2008
The second-generation Janus scorpionate ligand [HB(mtdaMe)3−] containing methyl-mercaptothiadiazolyl (mtdaMe) heterocyclic rings and (N,N,N-) and (S,S,S-) binding pockets has been prepared. The effect of methyl substitution versus the unsubstituted first-

Synthesis of pyrrolo[1,2-a]indole-1,8(5H)-diones as new synthons for developing novel tricyclic compounds of pharmaceutical interest [PDF]

, 2004
In the course of our work aimed at developing novel heterocycles of pharmaceutical interest, a new tricycle, the tetrahydropyrrolo[1,2-a]indole-1,8-dione, has been synthesized by an intramolecular Friedel-Crafts acylation, as a synthon suitable to be ...

Methylene Insertion into Nitrogen‐Heteroatom Single Bonds of 1,2‐Azoles via a Zinc Carbenoid: An Alternative Tool for Skeletal Editing

Advanced Science
The nitrogen‐heteroatom single bonds of 1,2‐azoles and isoxazolines underwent methylene insertion in the presence of CH2I2 (6 equiv.) and diethylzinc (3 equiv.) to produce a wide variety of the ring‐expanded six‐membered heterocycles.

Doping of Graphene Nanoribbons via Functional Group Edge Modification

, 2017
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone by modifying the 7-AGNR precursor.
