2-chlorocyclohexyl methyl

The acetylated products derived from higher alkenes are susceptible to protonation or solvolysis which produces carbenium ions that undergo Wagner-Meerwein hydride migrations. For example, on subjection of cyclohexene to standard Friedel-Crafts acetylation conditions (AcCl/AlCb, CS2—18 °C), products formed include not only 2-chlorocyclohexyl methyl ketone (in 40% yield) but also 4-chlorocyclohexyl methyl ketone. If benzene is added to the crude acetylation mixture and the tenperature is then increased to 40-45 °C for 3 h, 4-phenylcyclohexyl methyl ketone is formed in 45% yield (eq 3). ... [Pg.9]

Higher alkenes can be acetylated in synthetically useful yield by treatment with AcCl together with various mild Lewis acids. One that deserves prominent mention is EthyUUununum Dkhlo-ride (CH2CI2, It), which is useful for acetylation of all classes of alkenes (monosubstituted, 1,2-disubstituted, and trisubstituted). For example, cyclohexene is converted into an 82/18 mixture of 3-acetylcyclohexene and 2-chlorocyclohexyl methyl ketone in 89% combined yield. [Pg.18]

Methyl, ethyl and propyl perchlorates, readily formed from the alcohol and anhydrous perchloric acid, are highly explosive oils, sensitive to shock, heat and friction [1], Many of the explosions which have occurred on contact of hydrox-ylic compounds with cone, perchloric acid or anhydrous metal perchlorates are attributable to the formation and decomposition of perchlorate esters [2,3,4], Safe procedures for preparation of solutions of 14 sec-alkyl perchlorates are described. Heated evaporation of solvent caused explosions in all cases [5], l-Chloro-2-propyl, iram-2-chlorocyclohexyl, l-chloro-2-propyl, 1,6-hexanediyl, hexyl, and 2-propyl perchlorates, prepared by a new method, are all explosive oils [6],... [Pg.47]
