Organozinc compounds with acid halides

Formation of ketones by treatment of acid halides with organozinc compounds the use of p-hydroxy carbonyl chlorides to give p-hydroxy ketones, convertible into a,p-unsaturated ketones in boiling dilute sulfuric acid, is known as the Blaise-Maire reaction ... [Pg.138]

C-Alkylations have been performed with both support-bound carbon nucleophiles and support-bound carbon electrophiles. Benzyl, allyl, and aryl halides or triflates have generally been used as the carbon electrophiles. Suitable carbon nucleophiles are boranes, organozinc and organomagnesium compounds. C-Alkylations have also been accomplished by the addition of radicals to alkenes. Polystyrene can also be alkylated under harsh conditions, e.g. by Friedel-Crafts alkylation [11-16] in the presence of strong acids. This type of reaction is incompatible with most linkers and is generally only suitable for the preparation of functionalized supports. Few examples have been reported of the preparation of alkanes by C-C bond formation on solid phase, and general methodologies for such preparations are still scarce. [Pg.171]
