Journal Article
Kopp, R. O., Kleynemeyer, S. L., Groth, L. J., Ernst, M. J., Rupf, S. M., Weber, M., …Müller, C. (2024). Highly selective, reversible water activation by P,N-cooperativity in pyridyl-functionalized phosphinines. Chemical Science, 15, 5496-5506. https://doi.org/10.1039/d3sc05930h

Tetrapyridyl-functionalized phosphinines were prepared and structurally characterized. The donor-functionalized aromatic phosphorus heterocycles react highly selectively and even reversibly with water. Calculations reveal P,N-cooperativity for this p...

Phosphorus derivatives of mesoionic carbenes: synthesis and characterization of triazaphosphole-5-ylidene → BF 3 adducts † ‡. Chemical Communications, 59(68), 10243-10246. https://doi.org/10.1039/d3cc03268j

Trimethylsilyl-substituted triazaphospholes were synthesized by a [3+2] cycloaddition reaction between organic azides and (CH3)3Si-C ≡ P. In an attempt to isolate their N-alkylated products, the formation of BF3 adducts of unprecedented triazaphospho...

A diglyme solution of Na[cyclo-P5] (1) reacts with alkynes and isolobal nitriles and phosphaalkynes to afford the otherwise elusive (aza)phospholide anions 2 a–c, 4 a,b, and 6. The reaction of Na[cyclo-P5] with alkynes and nitriles was studied by mea... Read More about Reactivity of Sodium Pentaphospholide Na[cyclo ‐P 5] towards C≡E (E=C, N, P) Triple Bonds.
