2nd Annual #RCSAFellows Conference is underway in Tucson! Congrats to 2024 & 2025 Fellows, and thanks to our speakers, Facilitators & advisors for giving their time and advice so generously to help prepare these outstanding postdoctoral scholars for the faculty search process and the professoriate.

Thanks Joe!

Thanks Jose!

Happy to share that I’ve been selected to join the RCSA Fellows! I look forward to being a part of the program with @rescorp.org.

A Fresh Twist on the Phospha-(Aza)-Wittig Reaction The reactivity of an unsupported phosphinidene oxide, BnArNP═O (Bn = benzyl; Ar = bulky aryl group), as the electrophilic partner in Wittig reactions with ylides is described. Reactions with methylene-triphenylphosphorane (H2C═PPh3) and ethylidene-triphenyl-phosphorane (HMeC═PPh3), proceed as expected, giving rise to the phosphaalkene metathesis products and triphenylphosphine oxide. This reaction can be extended to other ylides such as N-(triphenylphosphoranylidene)methanamine (MeN═PPh3), to afford an aminoiminophosphane BnArNP═NMe. In these reactions the phosphinidene oxide plays the role of an electrophile, which would typically be the remit of an organic carbonyl in classical Wittig reactions. Further mechanistic insight into such transformations can be gained by altering the nature of the phosphorus-ylide. Upon reacting BnArNP═O with H2C═PMe3 (which possesses a smaller, more Lewis basic, phosphine) an alternative product is formed. This transformation supports the formation of a betaine intermediate that subsequently undergoes hydrogen-migration to afford an oxidized phosphorus(V) compound related to phosphorus acid.

Fresh out of the oven. Check out Chenyang’s most recent work in JACS (@jacs.acspublications.org). We explore the reactivity of a phosphinidene oxide as the electrophilic partner in Wittig transformations. Hope you enjoy.

Cyaphide group transfer from covalent metal complexes: contrasting pathways to transmetallation We describe two contrasting transmetallation reactions between the gold(i) cyaphide complex, Au(IDipp)(CP) (IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), and low oxidation state main-group and transition-metal complexes. The reactivity observed highlights the pseudo-halide character of the cyaph
