Similarly, bis(methylene) derivative (18) is formed in 5% yield, together with a 40% yield of azetane and 16% yield of an uncyclized intermediate, upon condensation of 3-chloro-2-chloro-methyl-l-propene with aniline (Equation (8)) <89JOU22io>. The same diazocine, as well as its N-Bu and N-S02QH4Me-4 analogues and (49), is also obtained through the use of xt-allyl palladium chemistry <90MI 924-01 >. 

Another type of elimination reaction is the reaction of 1 -(5-methyl-1 -phenyl- H-pyrazol-4-yl)ethanone with a Vilsmeier complex to give 3-chloro-3-(5-methyl-l-phenyl-l//-pyrazol-4-yl)propenal, which in turn undergoes dichloroformylation... 

The second point to explore involves carbocation stability. 2-Methyl-propene might react with H+ to form a carbocation having three alkyl substituents (a tertiary ion, 3°), or it might react to form a carbocation having one alkyl substituent (a primary ion, 1°). Since the tertiary alkyl chloride, 2-chloro-2-methylpropane, is the only product observed, formation of the tertiary cation is evidently favored over formation of the primary cation. Thermodynamic measurements show that, indeed, the stability of carbocations increases with increasing substitution so that the stability order is tertiary > secondary > primary > methyl.

The results of the olefin oxidation catalyzed by 19, 57, and 59-62 are summarized in Tables VI-VIII. Table VI shows that linear terminal olefins are selectively oxidized to 2-ketones, whereas cyclic olefins (cyclohexene and norbomene) are selectively oxidized to epoxides. Cyclopentene shows exceptional behavior, it is oxidized exclusively to cyclopentanone without any production of epoxypentane. This exception would be brought about by the more restrained and planar pen-tene ring, compared with other larger cyclic nonplanar olefins in Table VI, but the exact reason is not yet known. Linear inner olefin, 2-octene, is oxidized to both 2- and 3-octanones. 2-Methyl-2-butene is oxidized to 3-methyl-2-butanone, while ethyl vinyl ether is oxidized to acetaldehyde and ethyl alcohol. These products were identified by NMR, but could not be quantitatively determined because of the existence of overlapping small peaks in the GC chart. The last reaction corresponds to oxidative hydrolysis of ethyl vinyl ether. Those olefins having bulky (a-methylstyrene, j8-methylstyrene, and allylbenzene) or electon-withdrawing substituents (1-bromo-l-propene, 1-chloro-l-pro-pene, fumalonitrile, acrylonitrile, and methylacrylate) are not oxidized. 

The best alternative preparation of 3-chloro-2-(chloromethyl)-1-propene involves the direct chlorination of 3-chloro-2-methyl-1-propene using elemental chlorine.4 This method leads to a mixture of products that must be purified by a tedious spinning band distillation, and only yields 34% of the desired product. 

In another paper from the Jackson Laboratories of the du Pont Company (Calcott et al., 34) there is reported a repetition of some of the reactions of Simons and Archer, as well as additional ones. Mono-, di-, and 1,2,4,5 tetraisopropylbenzene were obtained from propylene and benzene both l -chloro-i-butylbenzene and di-(l/-chloro)-d-butylben-zene were obtained from 3-chloro-2-methyl-propene-l and benzene p-f-butyltoluene and di-i-butyltoluene were obtained from diisobutylene and toluene tetraisopropylnaphthalene was obtained from propylene and naphthalene naphthyl-stearic acid was obtained from oleic acid and naphthalene mixed isopropyltetrahydronaphthalene was obtained from propylene and tetrahydronaphthalene 2,4,6-triisopropylphenol was obtained from propylene and phenol a mixture of monoisopropylated m-cresols was obtained from propylene and wi-cresol and di-(s-hexyl)-diphenyl oxide was obtained from hexene-3 and diphenyl oxide.

Subsequently, a simpler procedure was devised for the preparation of (45) and the methyl derivative, chloro(acetylacetonato)-(ir-propen-2-ol)platinum(II) (48), which involved simply treating (43) with acetaldehyde or acetone in the presence of aqueous potassium hydroxide (45, 46). The respective a complexes are obtained as the potassium salts (46) and (47), most probably via attack by the a carbanion of the acetaldehyde or acetone on the platinum.
