Bis-chloro methylated benzene

All lation of palladium(II)-coordinated phosphane ligands with l,2-bis(chloro-methyl)benzene gives rise to new chelate rings and coincidentally to the macrocyclic complex [Pd(L1216)](HC03)2 (Eq. 5.5). 

We note that while tin reagents have often been employed for the organoboron halides/ the use of organostannanes as starting materials can also be applied to the synthesis of heavier group 13 derivatives. In the context of polyfunc-tional Lewis acid chemistry, this type of reaction has been employed for the preparation of ort/ o-phenylene aluminum derivatives. Thus, the reaction of 1,2-bis(trimethylstannyl)benzene 7 with dimethylaluminum chloride, methylaluminum dichloride or aluminum trichloride affords l,2-bis(dimethylaluminum)phenylene 37, l,2-bis(chloro(methyl)aluminum)phenylene 38 and 1,2-bis(dichloroalumi-num)phenylene 39, respectively (Scheme 16). Unfortunately, these compounds could not be crystallized and their identities have been inferred from NMR data only. In the case of 39, the aluminum derivative could not be separated from trimethyltin chloride with which it reportedly forms a polymeric ion pair consisting of trimethylstannyl cations and bis(trichloroaluminate) anions 40. 

Chlorine atoms in (trichloromethyl)benzenes which have fluoro, chloro, dichloromethyl, chloroformyl, cyano, isocyanato, jV-phthalimino or methyl substituents in the ring are substituted by fluorine using antimony(III) fluoride (Swarts reaction).3 4 2-(Trifluoromethyl)phen-yl isocyanate, 4-chloro-2-(trifluoromethyl)phenyl isocyanate, 2,4- and 2,5-bis(trifluoro-methyl)phenyl isocyanate, and 2,4-bis(trifluoromethyl)-l,5-phenylenc diisocyanate can be obtained in this way.5... 

Decomposition of benzoyl peroxide in hexamethyldisilane at 80° C gives, as major products, benzene, benzoic acid, l,2-bis(pentamethyldisilanyl)-ethane and benzylpentamethyldisilane (151). The reaction of hexamethyldisilane in carbon tetrachloride with benzoyl peroxide (at reflux temperature) and with di-tert-butyl peroxide (in a sealed tube at 129° C) gives (chloro-methyl)pentamethyldisilane as the main product arising from the silane (150). In no case are rearrangement products formed. Therefore, in solution at relatively low temperature, the pentamethyldisilanylmethyl radical does not undergo rearrangement as in the thermolysis. The main fate of this free radical is dimerization in the absence of solvent or chlorine atom abstraction when carbon tetrachloride is present. 

The inifer technique is specific for cationic and radical polymerizations. The most frequently used inifers in the first case are 1-chloro-l-methyl-ethylbenzene (a) 1,4-bis( 1-chloro-l-methylethyl)benzene (6) and l,3,5-tris(l-chloro-l-methyl)benzene (c)...

The reactions of trifluoromethylthiosilver with cobalt- (p. 326), palladium-, or platinum-halogen compounds (p. 341) have already been discussed." The reaction of silver(i) oxide with (CFg)2S(0) NH and with CFa SOg NH SOjF in benzene provides a route to silver bis(trifluoro-methyl)sulphur oxyimine [(CFg)2S(0) NAg] and CF3-S0g-NAgS02F, respectively. Each gives the A methyl compound on treatment with methyl iodide, and (CF8)3S(0) NAg is readily converted into the iV-chloro-com-pound by chlorine. ...

Sodium methyl mercaptide in xylene was reported to react (25°, 2 hr) in a stepwise fashion with 3,5-dichloro-as-triazine to yield the 3-methylthio-5-chloro and then (70°, 2 hr) the 3,5-bis-methylthio derivatives. However, the structure of the former is very likely to be 307. With dimethylamine in benzene (25°, 5 min), ethyleneimine in ether (25°, 3 min), and alcoholic ammonia (25°, few min), this dichloro derivative was assumed to form 3-amino derivatives. The high reactivity of as-triazines is demonstrated by the facile ethoxylation...

Di-/z-chloro-bis[(1 -ethyl-2-methyl-Ji-allyl) palladium], like most alkyl- and aryl-substituted 7r-allylchloropalladium dimers, is a yellow, crystalline, air-stable solid, which is soluble in organic solvents of medium polarity (acetone, dichloromethane, chloroform, benzene). The reactions of these compounds have been described in several reviews.17...
