Cyclododecanone, 2,12-dibromo

Cupric oxide [Copper oxide (CuO)], 10 Cyclodecanone, 111 Cyclododecanone, 108 Cyclododecanone, 2,12-dibromo-, 107 1 -Cy cloheptene, 1 -bromo-7 -acety loxy-[2-Cyclohepten-l-ol, 2-bromo-, acetate], 34... [Pg.139]

Sequential nucleophilic and electrophilic reactivity of a bromo lithio carbenoid is a feature of the transformation that permits a ring enlargement of cyclic ketones (Scheme 15)367,368 -pijug nucleophilic addition of dibromo lithio methane, which has been generated by deprotonation of dibromomethane, to cyclododecanone 119 leads to the... [Pg.874]

A useful one-carbon ring-expansion reaction which has been developed involves treatment of l-(dibromomethyl)-cycloalkan-l-ols with n-butyl-lithium in hexane to give the ring-expanded ketones, usually in excellent yield e.g. l-(dibromomethyl)-cyclododecan-l-ol, which was obtained by treating cyclododecanone with dibromo-methyl-lithium, gave cyclotridecanone in 89% isolated yield. ... [Pg.290]
