The Chemistry of Phenylimidotechnetium(V) Complexes with Isocyanides: Steric and Electronic Factors

open access: yesMolecules, 2022
Organometallic approaches are of ongoing interest for the development of novel functional 99mTc radiopharmaceuticals, while the basic organotechnetium chemistry seems frequently to be little explored. Thus, structural and reactivity studies with the long-

Synthesis and structure of a tetrahedral homoleptic CuI complex with xylyl isocyanide

open access: yesActa Crystallographica Section E: Crystallographic Communications
Treatment of the CuI precursor [Cu(NCMe)4]PF6 with excess (10 equivalents) of relatively bulky xylyl isocyanide formed a tetra(isocyanide) complex, namely, tetrakis(2,6-dimethylphenylisocyanide)copper(I) hexafluorophosphate, [Cu(C9H9N)4]PF6 or [Cu(CNXyl ...

Isocyanide-Based Multicomponent Reactions for the Synthesis of Heterocycles

open access: yesMolecules, 2015
Multicomponent reactions (MCRs) are extremely popular owing to their facile execution, high atom-efficiency and the high diversity of products. MCRs can be used to access various heterocycles and highly functionalized scaffolds, and thus have been ...

Isocyanide-Based Multicomponent Bicyclization with Substituted Allenoate and Isatin: Synthesis of Unusual Spirooxindole Containing [5.5]-Fused Heterocycle

open access: yes, 2016
A three-component bicyclization reaction of isocyanide, substituted allenoate, and isatin has been disclosed. This protocol is proposed to proceed through Michael addition, double cyclization, and [1,5]-hydride shift sequence, thus leading to the ...

On the reaction of diphenylketene with isocyanides

open access: yesOrganic & Biomolecular Chemistry, 2005
The products obtained from the reaction of diphenylketene with a variety of isocyanides are shown to depend heavily on the concentration of diphenylketene; a high concentration results in the precedented dioxolane derivatives, at much lower concentrations the reactions follow an alternative course and polycyclic beta-lactams are generated by a cascade ...
