Synthesis, Isolation, and Reactivity of a Phosphinidene Telluride We describe the synthesis and isolation of a phosphinidene telluride. This species acts as a versatile phosphinidene transfer reagent accompanied by the extrusion of elemental tellurium.

Here's the latest from Goicoechea Group alumnus and master synthetic chemist Chenyang Hu:

Some very elegant double-bond metathesis chemistry allows access to a phosphorus(III) telluride completing our collection of phosphorus-chalcogen double bonds.

Congratulations, Sandy. Big moment for both Jamie and you.

What better way to kick off my Bluesky account than at #ACSFall2025 meeting in Washington DC!

I’ll be giving a talk at the Main Group Chemistry session on some of my recent work @goicoecheagroup.bsky.social tomorrow (August 19) at 8:20 AM in East Salon B.

Can't wait to catch up with everyone!

Welcome to Bloomington, Kike!

Congratulations, Lucas! Fantastic work!!!

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.
