Hydrazines and azides via the metal-catalyzed hydrohydrazination and hydroazidation of olefins.
The discovery, study, and implementation of the Co- and Mn-catalyzed hydrohydrazination and hydroazidation reactions of olefins are reported. These reactions are equivalent to direct hydroaminations of C-C double bonds with protected hydrazines or hydrazoic acid but are based on a different concept in which the H and the N atoms come from two different reagents, a silane and an oxidizing nitrog...
متن کاملCoordination (co)polymerization of olefins
Introduction Middle 1950s may be treated as the beginning of the age of plastics – their global production in last 60 years have increased from approx. 1.5 mln to almost 290 mln tons. The dominating position in production and consumption of these materials for many years has been occupied by polyolefins (in Europe 48% from 57 mln tons of plastics) [1]. Forecasters predict that in coming years t...
متن کاملCopper-catalyzed trifluoromethylation of unactivated olefins.
The inclusion of fluorinated functional groups in small molecules has had a profound impact on the pharmaceutical, material, and agrochemical industries.[1, 2] In particular, the trifluoromethyl (CF3) substituent has emerged as an important functional group for the modulation of the physical properties in new pharmaceutical candidates as it has excellent metabolic stability, lipophilicity, and ...
متن کاملPalladium-Catalyzed Fluoroalkylative Cyclization of Olefins.
A palladium-catalyzed fluoroalkylative cyclization of olefins with readily available Rf-I reagents to afford the corresponding fluoroalkylated 2,3-dihydrobenzofuran and indolin derivatives with moderate to excellent yields is reported. This novel procedure provides an efficient method for the construction of Csp3-CF2 and C-O/N bonds in one step. A wide range of functional groups are tolerated. ...
