Lithium Chloride related reagents

Trialkylsilanes are usually formed by the addition of a lithium or Grignard reagent to the silyl chloride, and thus, discussions related to the formation of the silyl acetylene bond will be kept to a minimum. Silyl acetylenes are prepared from the alkynylcopper(I) reagents in the presence of PPh3, Zn or TMEDA in CH3CN at 100°, 36-98% yield. It is interesting to note that the... [Pg.654]

A further patent for the production of codeine, via codeinone, from thebaine has been published. " Codeine has been shown to be oxidized by manganese dioxide to 14-hydroxycodeinone the reaction is presumed to proceed via codeinone since 6-acetylcodeine is not affected by the same reagent. 6-O-Methanesulphonyl-dihydrocodeine has been shown to react with tetra-butylammonium fluoride, lithium chloride, and lithium bromide, with inversion at C-6, to give the related 6-halogeno-dihydrocodides, but when the ester is heated with sodium iodide in dimethylformamide the product is A -deoxycodeine (deoxycodeine-C) (143). Reductive amination of naltrexone with 2,2 -dihy-droxydiethylamine and sodium cyanoborohydride yields the 6-amino-compound (144 R = OH), which can be converted by carbon tetrachloride and tri-... [Pg.111]

Other useful organometallic reagents for the preparation of tertiary stibines or related heterocyclic compounds are compounds of lithium, aluminum, tin, copper, zirconium, and other metals. " In most cases, these metal compounds are reacted with antimony chlorides or bromides. Good yields of tertiary stibines were, however, also obtained by the interaction (equation 3) of triaUcylaluminium reagents and tris(dimethylamino)stibine. ... [Pg.219]

Angelini described the preparation of dihydro- 1,4-benzothiazine and related compounds from analogous esters by a two-stage reduction using tin and HC1 or lithium aluminum hydride.129 It is interesting to compare the reaction of 2-nitrophenol with similar reagents to produce benzooxazine derivatives. 2-Nitrophenol reacts with a-bromoethyl acetate, and the adduct is cyclized with zinc and ammonium chloride to the hydroxamic derivative 85.130 The adduct with phenacyl chloride has been similarly cyclized under a variety of conditions.131,132... [Pg.160]
