Vaska’s complex- Reagent of the month

Iridium is ubiquitous in organic synthesis. In the last decade alone we have seen its impact as a phtoredox catalyst for a wide range of light-driven reactions that are difficult to achieve using traditional synthetic methods.1 In addition, iridium has rich utility in C-H activation chemistry- a recent review by Cramer highlighting chiral complexes as

Synthesizing Aromatic Nitriles via Cyanation

Cyanation of aromatic/heteroaromatic halides/pseudohalides is still not always a straightforward transformation, especially if the reaction needs to be scaled up. 2 Ar-X  +  Zn(CN)2  ®  2 ArCN  +  ZnX2 Workers at BMS have recently published a paper where they describe an improved protocol for this transformation1. They found that Pd2(dba)3 with XantPhos, Zn(CN)2 and i-Pr2NEt
