Palladium-catalyzed cross coupling reactions of 4-bromo-6H-1,2-oxazines
Beilstein Journal of Organic Chemistry, 2009 A number of 4-aryl- and 4-alkynyl-substituted 6H-1,2-oxazines 8 and 9 have been prepared in good yields via cross coupling reactions of halogenated precursors 2, which in turn are easily accessible by bromination of 6H-1,2-oxazines 1. Lewis-acid promoted

Aluminum-Catalyzed Cross Selective C3–N1′ Coupling Reactions of N-Methoxyindoles with Indoles
Chemistry, 2023 C3–N1′ bond formation of bisindoles has been a great challenge due to the intrinsic reactivity of indoles as both C3 and N1-nucleophilic character.

Relay cross metathesis reactions of vinylphosphonates
Beilstein Journal of Organic Chemistry, 2014 Dimethyl (β-substituted) vinylphosphonates do not readily undergo cross metathesis reactions with Grubbs catalyst and terminal alkenes. However, the corresponding mono- or diallyl vinylphosphonate esters undergo facile cross metathesis reactions.

Synthesis of chiral germanium center enabled by poly-deborylative alkylation and desymmetrization
Nature CommunicationsChiral germanium centers are historically undervalued due to their extremely limited synthetic accessibility. Although germanium shares similar chemical properties with silicon, synthesizing chiral germanium centers proves significantly more challenging.

(n,α) reactions cross section research at IPPE
EPJ Web of Conferences, 2012 An experimental set-up based on an ionization chamber with a Frisch grid and wave form digitizer was used for (n,α) cross section measurements. Use of digital signal processing allowed us to select a gaseous cell inside the sensitive area of the ...
