Carbenes (R2C:), compounds with a divalent carbon atom containing only six valence shell
electrons, have evolved into a broader class with the replacement of the carbene carbon or …

Triplet states have been widely studied in phosphorescent molecules, lanthanide complexes
and triplet–triplet annihilation systems, in which they have a critical role in energy transfer …

Summary Pnictinidenes (RE, where E= P, As, Sb, or Bi) are long-sought-after reactive
species. They feature either a singlet or triplet ground state depending on the electronic …

Vinyl pnictinidenes are an elusive family of molecules that have been suggested as key
intermediates in multiple chemical reactions and commonly display a predisposition toward …

We report on the (tert-butyl) isocyanide-catalysed isomersation of a phosphaethynolato-
borane,[B] OCP ([B]= N, N′-bis (2, 6-diisopropylphenyl)-2, 3-dihydro-1H-1, 3, 2-diazaboryl) …

Carbonyl nitrenes are versatile intermediates that have been extensively characterized;
however, their phosphorus analogues remain largely unknown. Herein, we report the …

A room-temperature-stable crystalline 2 H-phosphirene (1) was prepared by treatment of an
electrophilic diamidocarbene with tert-butylphosphaalkyne. Compound 1 is shown to react …

Carbenes and nitrenes are key intermediates involved in numerous chemical processes,
and they have attracted considerable attention in synthetic chemistry, biochemistry, and …

The perfluorinated silylphosphinidene, F3SiP, in the triplet ground state is generated by the
reaction of laser-ablated silicon atoms with PF3 in solid neon and argon matrices. The …

Phosphanorcaradienes are an appealing class of phosphorus compounds that can serve as
synthons of transient phosphinidenes. However, the synthesis of such species is a …
