Phosphorus derivatives of mesoionic carbenes: synthesis and characterization of triazaphosphole-5-ylidene → BF 3 adducts † ‡ (2023)
Journal Article
Dettling, L., Limberg, N., Küppers, R., Frost, D., Weber, M., Coles, N. T., …Müller, C. (in press). 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...

Phospholenes from Phosphabenzenes by Selective Ring Contraction (2022)
Journal Article
Lin, J., Coles, N. T., Dettling, L., Steiner, L., Witte, J. F., Paulus, B., & Müller, C. (2022). Phospholenes from Phosphabenzenes by Selective Ring Contraction. Chemistry - A European Journal, 28(72), Article e202203406. https://doi.org/10.1002/chem.202203406

A 3-amino-functionalized phosphabenzene (phosphinine) has been synthesized and structurally characterized. The pyramidalized nitrogen atom of the dimethylamino substituent indicates only a weak interaction between the lone pair of the nitrogen atom a...

Reactivity of Sodium Pentaphospholide Na[cyclo ‐P 5] towards C≡E (E=C, N, P) Triple Bonds (2022)
Journal Article
Petrov, A., Conrad, L., Coles, N. T., Weber, M., Andrae, D., Zagidullin, A., …Müller, C. (2022). Reactivity of Sodium Pentaphospholide Na[cyclo ‐P 5] towards C≡E (E=C, N, P) Triple Bonds. Chemistry - A European Journal, 28(67), Article e202203056. https://doi.org/10.1002/chem.202203056

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.

Journal Article
Lin, J., Wossidlo., F., Coles, N. T., Weber, M., Steinhauer, S., Böttcher, T., & Müller, C. (2022). Borane Adducts of Aromatic Phosphorus Heterocycles: Synthesis, Crystallographic Characterization and Reactivity of a Phosphinine‐B(C 6 F 5 ) 3 Lewis Pair. Chemistry - A European Journal, 28(7), Article e202104135. https://doi.org/10.1002/chem.202104135

A phosphinine-borane adduct of a Me3Si-functionalized phosphinine and the Lewis acid B(C6F5)3 has been synthesized and characterized crystallographically for the first time. The reaction strongly depends on the nature of the substituents in the α-pos...
