DOI: 10.1002/ejoc.201601446
Abstract: Synthetic routes to α,α-disubstituted allylamines have been examined. Racemic compounds were conveniently prepared by thermal Overman rearrangements of primary allyl alcohols with trisubstituted double bonds, but rearrangement of these substrates by the only commercially available… read more here.

Abstract: Abstract Reactions of benzyne with ester derivatives of spiro[2.4]hepta-4,6-dien-1-ylmethanol were performed. By rearrangement reaction of cyclopropyl methanol units of ((1s*,1′R*,2R*,4′S*)-1′,4′-dihydrospiro[cyclopropane-1,9'-[1,4]methanonaphthalen]-2-yl) methyl 3,5-dinitrobenzoate (13) and its isomer (14), corresponding allyl chlorides were obtained. Two rearrangement products… read more here.

DOI: 10.1016/j.tet.2019.04.062
Abstract: Abstract The ligand-redistribution reactions of aryl- and alkoxy-hydrosilanes can potentially cause the formation of gaseous hydrosilanes, which are flammable and pyrophoric. The ability of generic nucleophiles to initiate the ligand-redistribution reaction of commonly used hydrosilane… read more here.

DOI: 10.1039/c9cc03809d
Abstract: Benzyl thioethers undergo rhodium(ii) catalyzed sigmatropic rearrangement reactions with aryldiazoacetates. Depending on the solvent and the electronic properties of the sulfide, the intermediate ylide undergoes either [1,2]- or [2,3]-sigmatropic rearrangement reactions in high yields. read more here.

DOI: 10.1039/d1sc00495f
Abstract: Herein, we report on our studies on the reaction of organoselenium compounds with triazoles under thermal conditions using simple Rh(ii) catalysts. These reactions do not provide the product of classic rearrangement reactions. Instead two different… read more here.
