Yangguangyan Zheng, Bukeyan Miao, Anni Qin, Junzhe Xiao, Qi Liu, Gen Li, Li Zhang, Fang Zhang, Yinlong Guo, Shengming Ma. Clément F. Heinrich, Michel Miesch, Laurence Miesch. Biru et al. (A) Thiol reactions: (a) thiol-maleimide Michael-type addition; (B) disulfide exchange reaction; and (C) disulfide reduction. Step (2) Y-C-C + - + Z → Y-C-C-Z Step 2 is also found in a SN1 reaction. If HCl adds to an unsymmetrical alkene like propene, there are two possible ways it could add. Min Wang, Zheng-Li Liu, Xiang Zhang, Pan-Pan Tian, Yun-He Xu, and Teck-Peng Loh . Allylic metal species can be used to prepare allylic amines through electrophilic amination. Aryl and heteroaryl organometallic reagents undergo many of the same transformations as their aliphatic counterparts. Li-Na Guo, Xin-Hua Duan, and Yong-Min Liang . For example, in well-aerated tropical soil environments, the degradation half-life of oxidation-resistant elemental carbon could be less than 50 years [111]. Cleavage of oxygen–sulfur double bonds and carbon–sulfur bonds: unusual highly selective electrophilic addition of allenylic sulfoxides. From here, the reaction then proceeds via two distinct stages: Structural rearrangement via intermediates with epoxy/hemiketal groups to yield oxidised fullerene anions; These fullerene anions then undergo nucleophilic additions with H2O2 to yield stable PHF products. The possible transformations of CNTs in natural or engineered systems can change properties of CNTs and consequently affect their mobility and bioavailability. Rong Zeng, Chunling Fu, and Shengming Ma . Cu(I)-catalyzed coupling of diaryldiazomethanes with terminal alkynes: an efficient synthesis of tri-aryl-substituted allenes. Due to the presence of pi electrons they show addition reactions in which an electrophile attacks the carbon-carbon double bond to form the addition products. Regiocontrolled Halohydroxylations of Bicyclic Vinylidenecyclopropanes: A Versatile Strategy for the Construction of Diverse Highly Functionalized Carbocyclic Scaffolds. One-pot cascade reactions of 1-arylpenta-3,4-dien-2-ones leading to 2-arylphenols and dibenzopyroanones. An Electrophilic Cyclization Protocol for Convenient Highly Regioselective Synthesis of 3-Sulfonylfuran-2(5H)-ones from 2-Sulfonylallenoates. CuI-Catalyzed Synthesis of Functionalized Terminal Allenes from 1-Alkynes. Although MAL groups can also react with other nucleophiles, such as amines, they show specificity toward the thiols in the pH range of 6.5–7.5 (Partis et al., 1983). Tosylhydrazones, Terminal Alkynes, and Allyl Halides. The primary application of alkylmetal reagents in electrophilic amination reactions is the synthesis of hindered amines, many of which are difficult to prepare through nucleophilic displacement with an alkyl halide (nucleophilic amination). A Novel Iodine-Promoted Tandem Cyclization: An Efficient Synthesis of Substituted 3,4-Diiodoheterocyclic Compounds. Enantioselective Palladium-Catalyzed Carbonylative Carbocyclization of Enallenes via Cross-Dehydrogenative Coupling with Terminal Alkynes: Efficient Construction of α-Chirality of Ketones. Reprint of: Recent advances in the functionalization of allenes via radical process. Progress in fluoroalkylation of organic compounds via sulfinatodehalogenation initiation system. A hydrogen atom joins to one of the carbon atoms originally in the double bond, and a halogen atom to the other. Xiao-Wen Zheng, Ling Nie, Ya-Ping Li, Shao-Jing Liu, Feng-Yue Zhao, Xin-Yu Zhang, Xing-Dong Wang, Tao Liu. In terms of reaction conditions and the factors affecting the rates of the reaction, there is no difference whatsoever between these alkenes and the symmetrical ones described above. via
