Alkyl bromides. Alcohols are converted into bromides by reaction with bromotrimethylsilane (1.5-4 equiv.) in CHCI3 at 25-50° (equation I). The reaction occurs with inversion. Tertiary and benzylic alcohols react more rapidly than primary or secondary alcohols. Bromides are not formed under the same conditions from Irimethylsilyl ethers of alcohols. However, trimethyl orthoformate is converted into methyl formate, HC(OCH3)3 —s HCOOCH3. Unlike iodotrimethylsUane, the bromosilane does not dealkylate esters, ethers, or carbamates. [Pg.343]

The nitroveratrole group can be prepared by direct acid-catalyzed esterification with the benzyl alcohol. It is cleaved photochemically by irradiation at 420 nm. It is cleaved in the presence of the l,2-dihydroxy-2,4,4-trimethyl-3-pentanone, which... [Pg.615]

Benzylic carbocations are also stabilized by complexation to chromium and a number of interesting reactions have been reported. Again, reaction of the carbocations with nucleophiles occurs from the exo face of the complex, relative to the metal. Carbocations are readily formed by treatment of benzylic alcohols with a strong acid, such as sulfuric acid, tetrafluoroboric acid, or borontrifluoride etherate. The cation can be trapped with water, alcohols, nitriles, and mono-or disubstituted amines to form alcohols, ethers, amides, and di- or trisubstituted amines respectively. Scheme 96 illustrates the formation of a benzylic carbocation followed by intramolecular trapping, resulting in a net inversion of stereochemistry. Benzylic acetates react with trimethyl aluminium introducing a methyl group from the opposite face of the metal. [Pg.3237]

In most cases low-volatility organic coalescing agents such as Texanol (2,2,4-trimethyl-l,3-pentanediol monoisobutyrate, Eastman Chemical Co.), ethylene/ propylene glycols, or benzyl alcohol are added to cause high Tg polymers to coalesce at room temperature. Hydrocarbons are effective when the copolymer contains a substantial fraction of higher alkyl monomer such as ethylhexyl acrylate. [Pg.3530]

Trimethylsilyl iodide 17, which can be generated in situ by reaction of trimethyl-silyl chloride (TCS) 14 with Nal in acetonitrile [1], converts alcohols 11, in high yields at room temperature, into their iodides 773a, HI, and hexamethyldisiloxane (HMDSO) 7 [1-8, 12]. Likewise esters such as benzyl benzoate are cleaved by Me3SiCl 14/NaI in acetonitrile under reflux [Ij. Reactions of alcohols 11 with trimethylsilyl bromide 16 in chloroform or, for in situ synthesis of 16 from liBr and TCS 14 in acetonitrile and with HMDS 2 and pyridinium bromide perbromide, proceed only on heating in acetonitrile or chloroform to give the bromides 773 b in nearly quantitative yield [3, 8, 12] (Scheme 6.1). [Pg.135]
