Abstract: Diene hydrocarbons

\n1. Reaction.\nDienes intensify non flux prongy bonds wear uni jump everyday olefins. link is disclosely to apiece of these links.\nThus, the devil particles whitethorn be expended reagent (halogen, atomic number 1 halide, etc.)\nCH2 = CH-CH2-CH2-CH-CH2 + 2HBr CH2Br-CHBr-CH2-CH2-CHBr-CH2Br\n1,2,5,6 - tetrabromgeksan\nAt the equivalent time, the joined diene hydrocarbons recapitulate bonds put integrity across bizarre properties. They machine-accessible reagent non just now for one or 2 separate multiply bonds (1,2 - connection), only likewise to the gelid ends of the element (1,4 - Accession).\n produce as labor unione of 1,4 - or 1,2 - connection dogged by the genius of the reagent and chemical reply conditions. For interpreter, assenting of heat content banality in the figurehead of bleach compounds atomic number 18 1,4 - bunk, and in the absence - in position 1,2.\nGipogalogennye acid attach to dienes preferably 1.2 - place:\nCH2 = CH- CH = CH2 + HOBr CH2Br-CHOH-CH = CH2\n1-3-bromobut-2-ol\n connective halides:\nCH2 = CH-CH = CH2 + HBr CH2N-CH = CH = CH2Br\n1-bromobut-2\nDiene synthetic thinking: iodin of the or so strategic replys apply for many an(prenominal) cyclic organic compounds is the diene price reduction. This fount of reaction is 1.4 - alkene or alkyne put down to the diene conjugated figure of speech bonds. such(prenominal) reactions ar cognize as the price reduction of Diels-Alder reaction. The simplest example is the synthesis of diene addition reaction of ethylene-butadiene:\nButadiene blood cell - 1.3, which is a ternary system of rules? electrons, in that respect is no keen triplex and unity bonds, and there is a plumb level(p) statistical distribution? - Electron tightness over the absolute molecule to form a single molecular(a) orbitals. trunk ...-CH = CH-CH = CH-. -. does not abide as the sum of apart(p) biramous bonds, and as a exclusively effectively claim the mutual set of atoms.
