    Professor Lu's research on cobalt featured in JACS virtual issue

The Journal of the American Chemical Society (JACS) has published an Americal Chemical Society select virtual issue based on the outstanding work of young investigators published in 2017 in its publication. According to JACS, "The 2018 JACS Young Investigators Virtual Issue is a collection of articles and communications that highlights premier research in diverse topical areas from around the world that is of broad interest to the contemporary readership of JACS. These carefully selected publications were chosen by the appropriate, knowledgeable JACS Editors on the basis of reviewer input and editorial evaluation." One of the featured articles encompasses Professor Connie Lu's research on the "Stable Dihydrogen Complexes of Cobalt(−I) Suggest an Inverse trans-Influence of Lewis Acidic Group 13 Metalloligands."

William Jones, JACS associate editor, wrote about Lu's research: "Transition metal dihydrogen adducts are proposed intermediates in a variety of hydrogenation processes. This article describes a fascinating series of dihydrogen complexes at a d10 cobalt(–I) center. While bona fide examples of cobalt-H2 adducts are limited, examples of any d10-H2 complexes are quite rare, all involving Ni(0). This work builds a case for a strong inverse trans-influence of the Lewis acidic group 13 Z-type ligand being used to promote H2 binding. Lu's group demonstrates a key feature of ligand design (to incorporate a σ-acceptor trans to the metal binding pocket) that can be used to promote H2 binding to a base metal.

Co-authors of the article were graduate student Matthew Vollmer and Jing Xie, Ph.D.
