Dibromomethane: Methane, dibromo

Beilstein Handbook Reference) AI3-52311 BRN 0969143 CCRIS 939 Dibromomethane EINECS 200-824-2 HSDB 1334 Methane, dibromo- Methylene bromide Methylene dibromide NSC 7293 RCRA waste number U068 UN26M. Used in the production of leaded gasoline, as a fumigant for stored products and as a nematocide. Also used in the manufacture of fire retardent chemicals. Dense, mobile liquid mp = -52.5 bp = 97 d = 2.4969 soluble in organic solvents, slightly soluble in H2O. [Pg.404]

Preparation of the Active Polvformals under Phase-transfer Catalysis. The polycondensation of DHTN or DHCH with dibromo- or dichloro-methane was carried out under phase transfer catalysis as shown in equations 2 and 3. Best results were obtained with dibromomethane, 60% aqueous KOH and tetrabutyl ammonium bromide. [Pg.104]

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]

Other Methyldiphenylsilylations. Oshima and co-workers have synthesized dibromobis(methyldiphenylsilyl)methane (49) and dibromo(methyldiphenylsilyl)methane (50) from tetra-and dibromomethanes, respectively (eqs 30 and 31). The preparation of dichlorobis(methyldiphenylsilyl)methane from dichloromethane is also reported. ... [Pg.386]
