Calcium biphenyl

Optically active l-halo-l-mefhyl-2,2-diphenylcyclopropanes 61 are used as probes to investigate the mechanisms of calcium reduction [39]. Treatment of 61 with calcium biphenyl (Ca(BPh)2) or calcium naphthalene (Ca(NPh)2) then addition of CO2 gives a mixture of cyclopropane derivative 62 and the corresponding carboxylic acid 63 (Scheme 4.17). Walborsky and Hamdouchi have provided evidence showing that these reactions occur by single electron transfer to yield free radicals... [Pg.167]

A. Active calcium. Freshly cut lithium (41.7 mg, 6.01 mmol) and biphenyl (1.020 g, 6.61 mmol) in freshly distilled tetrahydrofuran (THF, 15 mL) (Note 1) are vigorously stirred at room temperature under argon (Note 2) until the lithium is completely... [Pg.226]

The API fenoprofen calcium is a diaryl ether. Degradation of fenopro-fen under intense ultraviolet light in solution yields a mixture of isomeric biphenyls via a photo-Fries rearrangement mechanism (Fig. 76) (117). [Pg.89]

Decinine (2) was prepared similarly by Lantos and Loev (80), from the biphenyl aldehyde (169). Calcium hydroxide-catalyzed condensation with pelletierine afforded biphenyl quinolizidone (172) in 20% yield. This compound was obtained in better yield from the acid-catalyzed epimerization of the cis-fused diastereomer (173) of the decamine synthesis (68). [Pg.311]

The biphenyl alkaloid decinine (37) was synthesized by a route similar to that employed for methyldecinine cf. Vol. 6). The hydroxy-group was protected as its methyl sulphonate ester and calcium hydroxide was used in the reaction of the... [Pg.77]

Finally, lipid-soluble chemicals like the insecticide DDT, polychlorinated biphenyls, and methylmercury are excreted readily as dissolved chemicals into milk fat droplets. Lead is secreted into milk using the same transport system as calcium. Nursing mothers may therefore transfer environmental contaminants to their infants - not to the point, however, of negating the well-established benefits of breastfeeding. [Pg.1110]
