Abstract Phosphanorcaradienes are an appealing class of phosphorus compounds that can serve as synthons transient phosphinidenes. However, the synthesis such species is a formidable task owing to their intrinsic high reactivity. Herein we report straightforward synthesis, characterization and reactivity studies phosphanorcaradiene, in which one benzene rings flanking fluorenyl substituents intramolecularly dearomatized through attachment atom. It facilely obtained by reduction phosphorus(III) dichloride precursor with potassium graphite. Despite being thermally robust, it acts synthetic equivalent phosphinidene. reacts trimethylphosphine isonitrile yield phosphanylidene-phosphorane 1-phospha-3-azaallene, respectively. When treated two molar equivalents azide, iminophosphane bis(imino)phosphane isolated, Moreover, capable activating ethylene alkyne afford [1 + 2] cycloaddition products, well oxidative cleavage Si–H N–H bonds secondary phosphines. All reactions proceed smoothly at room temperature without presence transition metals. The driving force for these most likely ring-constraint three-membered PC 2 ring recovery aromaticity ring.

Abstract Imidazolium‐dithiocarboxylate zwitterions (NHC ⋅ CS 2 ), a novel organocatalyst that derived from N‐heterocyclic carbene (NHC), was used to activate cyclopropenones. Under the catalysis of 10 mol% NHC 2, range phenols, alcohols, primary and secondary amines react with cyclopropenones produce trisubstituted α , β ‐unsaturated esters amides in 46–95% yield. More than 68 products, including 7 natural product derivatives have been synthesized through this method. Mechanism study showed act as Lewis base C=C double bond trigger ring‐opening reaction. HRMS analysis indicated formation key adduct cyclopropenone. importantly, demonstrated completely different catalytic activity catalysts, latter one cannot catalyse these reactions.

Abstract A bisphosphirane‐fused anthracene ( 5 ) was prepared by treatment of a sterically encumbered amino phosphorus dichloride 3 with Mg ⋅ THF =anthracene). X‐ray diffraction analysis revealed pentacyclic framework consisting two phosphirane rings fused to the in trans ‐fashion. Compound has been shown be an efficient phosphinidene synthon, readily liberating transient units for subsequent downstream bond activation via reductive elimination under mild conditions. The formal oxidative addition H 2 and E−H (E=Si, N, P) bonds liberated provided diphosphine substituted phosphines. Furthermore, transfer alkenes alkynes smoothly yielded corresponding phosphiranes phosphirenes. mechanism investigated density functional theory (DFT) calculations.
