Application of this strategy to the synthesis of more complex compounds produced the thieno[2,3-, ]thiophene 342 <2000PS259>. Thus, the diamine 569 treated with NaOH and CS2 in dimethylformamide (DMF) provided the corresponding bis(disodium dithiocarbaminate) 570, which was alkylated with 1,2-dibromethane to give the final product 342 (Scheme 79).

Aredia, pamidronate disodium (APD), is a bone-resorption inhibitor used to treat hypercalcemia associated with malignancy and osteolytic bone lesions associated with multiple myeloma, metastatic breast cancer, and moderate to severe Paget s disease of bone. Aredia, a member of the group of chemical compounds known as bisphosphonates, is an analog of pyrophosphate. Pamidronate disodium is designated chemically as phosphonic acid (3-amino-l-hydroxypropylidene) bis-, disodium salt, pentahydrate, (APD). 

Solvent for Displacement Reactions. As the most polar of the common aprotic solvents, DMSO is a favored solvent for displacement reactions because of its high dielectric constant and because anions are less solvated in it (87). Rates for these reactions are sometimes a thousand times faster in DMSO than in alcohols. Suitable nucleophiles include acetyUde ion, alkoxide ion, hydroxide ion, azide ion, carbanions, carboxylate ions, cyanide ion, hahde ions, mercaptide ions, phenoxide ions, nitrite ions, and thiocyanate ions (31). Rates of displacement by amides or amines are also greater in DMSO than in alcohol or aqueous solutions. Dimethyl sulfoxide is used as the reaction solvent in the manufacture of high performance, polyaryl ether polymers by reaction of bis(4,4 -chlorophenyl) sulfone with the disodium salts of dihydroxyphenols, eg, bisphenol A or 4,4 -sulfonylbisphenol (88). These and related reactions are made more economical by efficient recycling of DMSO (89). Nucleophilic displacement of activated aromatic nitro groups with aryloxy anion in DMSO is a versatile and useful reaction for the synthesis of aromatic ethers and polyethers (90). 

EDA reacts readily with two moles of CS2 in aqueous sodium hydroxide to form the bis sodium dithiocarbamate. When aqueous ammonia and 2inc oxide (or manganese oxide or its hydrate) is used with a basic catalyst, the 2inc (or manganese) dithiocarbamate salt is isolated. Alternatively, the disodium salt can react with ZnSO or MnSO followed by dehydration in an organic solvent to yield the same salts (48—50).

The aqueous solution is then concentrated to dryness at an outside temperature of 40° to 45°C and at low pressure. The residue, obtained by drying in a vacuum at 40° to 45°C is triturated in a mortar with ethyl ether and, after filtration, is extracted with 3,400 ml boiling absolute ethanol. The ethanol extract is separated from the undissolved part by filtration, cooled and the product which crystallizes by cooling is filtered and dried at 40°C in a vacuum. In that manner the disodium (4,4 -disulfoxy-diphenyl)-(2-pyridyl)-methane bi-hydrate is obtained, which takes the form of a white solid, according to U.S. Patent 3,528,986. 

Tin phthalocyanines can be prepared using tin(II)110 or -(IV)154 chlorides. The reaction can be performed in 1-chloro-1 10,1 37,1 55 or 1-bromonaphthalene,154 starting from phthalonitrile110137154,155 or phthalic anhydride. In the second case, urea and ammonium molyb-date(VI) arc added.137 The central tin atom can also be introduced into metal-free phthalocyanine by the reaction with tin(IV) chloride in dimethylformamide.141 Treatment of PcSnCl2 with disodium phthalocyanine in refluxing 1-chloronaphthalenc forms a sandwich-like bis-(phthalocyanine) Pc2Sn.154...

Disodium glyphosate has been reacted with activated heteroaryl halides, such as 2-chlorobenzothiazole or 2-chlorobenzoxazole 79, in aqueous alcohol at reflux to produce the N heteroaryl glyphosate derivadves 80 (2). Improved yields have often obtained in these reactions using the more soluble bis-quatcmary ammonium salt of glyphosate derived from tetrabutylammonium hydroxide (2). 

Brown HT (El55, Cl Food Brown 3, Chocolate brown) is a bis azo dye, with the chemical name disodium 4,4 -(2,4-dihydroxy-5-hydroxymethyl-l,3-phenylene-bisazo) di(naphthalene-l-sulfonate). The calcium and potassium salts are also permitted. Brown HT is a reddish-brown powder or granules, soluble in water, insoluble in ethanol, with a maximum absorption in water at 460 nm, pH 7, = 403). 

Selection of appropriate conditions to modify polymers is facilitated by preliminary studies with well designed model compounds. The work with model systems is critical when studying condensation polymers because the main chain linkages have proved to be remarkably labile under certain conditions. Condensation of 4-chlorophenyl phenyl sulfone with the disodium salt of blsphenol-A yields 2,2-bis[4 -(4"-phenylsulfonylphenoxyl)phenyl] propane, T, an excellent model for the poly(arylene ether sulfone) substrate. Conditions for quantitative bromination, nitration, chloro-methylation, and aminomethylation of the model compound were established. Comparable conditions were employed to modify the corresponding polymers.

BNCT sensitisers are designed with neutron capture in mind, but those that are porphyrin/ phthalocyanine-based may show PDT activity. An example is the disodium (or dipotassium) salt of the tetrakis-carborane ester (58) derived from 3,8-bis(l,2-dihydroxyethyl)deuteroporphyrin.298 This is water soluble and tumor selective, showing high tumor/normal brain ratios.299 Photophysical properties are similar to other water-soluble porphyrins in rat glioma cells, specific localization in mitochondria is observed.300...

Procedure Weigh accurately 0.20 g of glycobiarsol into a 250-ml conical flask and add 10.0 ml of 0.05 M disodium edetate. Warm the contents of the flask over a water-bath until glycobiarsol gets dissolved completely and then cool the contents to the room temperature (25°C). Add to it 10.0 ml of acetic acid-ammonium acetate buffer, 25.00 ml of alcohol and 2 ml of dithizone solution as an indicator. Titrate the excess of disodium edetate with 0.025 M zinc sulphate until the resulting solution turns rose pink in colour. Each millilitre of 0.05 M disodium edetate consumed is equivalent to 10.45 mg of Bi.
