A Pd-catalyzed intermol. asym. spiroannulation of 2,3-disubstituted indoles with internal alkynes was developed for the efficient construction of indoline structures with a C2-quaternary stereocenter. Stereospecific aza-semipinacol rearrangement of these indoline derivatives under acidic conditions afforded indolenine products bearing a C3-quaternary stereocenter, where the migrating group could be controlled by the reaction sequence. The asym. spiroannulation together with the subsequent aza-semipinacol rearrangement enabled a divergent access to dearomatized indole derivatives with either a C3- or a C2-quaternary stereocenter. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7Recommanded Product: 85118-24-7).

2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.

2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon闁艰京鐗梤omine bond is electrophilic in nature. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Name: 2-Bromo-4-(trifluoromethyl)benzaldehyde

Intramolecular Acetyl Transfer to Olefins by Catalytic C-C Bond Activation of Unstrained Ketones was written by Rong, Zi-Qiang;Lim, Hee Nam;Dong, Guangbin. And the article was included in Angewandte Chemie, International Edition in 2018.SDS of cas: 85118-24-7 This article mentions the following:

A rhodium-catalyzed intramol. acetyl-group transfer was achieved through a “cut and sew” process. The challenge arises from the existence of different competitive pathways. Preliminary success was achieved with unstrained enones that contain a biaryl linker. The use of an electron-rich N-heterocyclic carbene (NHC) ligand is effective to inhibit undesired 灏?hydrogen elimination. Various 9,10-dihydrophenanthrene derivatives can be prepared with excellent functional-group compatibility. The ¹³C-labeling study suggests that the reaction begins with cleavage of the unstrained C-C bond, followed by migratory insertion and reductive elimination. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7SDS of cas: 85118-24-7).
