Novel layered lead(II) aminodiphosphonates with carboxylate-sulfonate and 1,3,5-benzenetricarboxylate ligands as pendant groups or intercalated species

The hydrothermal reaction of lead(II) carbonate with 3-sulfobenzoic acid, 3-HO3S-C6H4-CO2H, and isopropylimino-bis(methylenephosphonic acid), (CH3) 2CHN(CH2PO3H2)2 (H 4L1), gave a new layered lead(II) carboxylate-phosphonate, Pb7(S-O3S-C6H4-CO 2)(L1)3(H2O)2· 2H2O (1), whereas the hydrothermal reaction of lead(II) carbonate with 1, 3,5-benzenetricarboxylic acid (H3BTC) and N-cyclohexyUmino-bis(methylenephosphonic acid), C6H 11N(CH2PO3H2)2 (H 4L2), afforded a layered complex, Pb3(HL 2)(H2L2)(H2BTC)-(H 2O)·H3BTC·H2O (2). The structure of complex 1 contains 〈010〈 lead(II) carboxylate-phosphonate hybrid layers, with the sulfonate group of the carboxylate-sulfonate ligand as the pendant group. In complex 2, the lead(II) ions are interconnected through bridging diphosphonate ligands, and results in the formation of a lead(II) diphosphonate slab, which are further interlinked via hydrogen bonds between non-coordinated phosphonate oxygen atoms to form a 〈001〈 layer. The doubly protonated H2BTC anion is bidentately chelated to a lead(II) ion through a carboxylate group, whereas the neutral H3BTC ligand is intercalated between two layers, forming hydrogen bonds with the non-coordinated carboxylate groups of the H2BTC anion.

Synthesis, crystal structure, cholinesterase inhibitory activity, evaluation of insecticidal activities, and computational studies of new phosphonic acids

Abstract: In an attempt to obtain the modified and novel insecticides with low human toxicity, a series of novel mono-, bis-, and tetraphosphonic acid derivatives were designed and characterized by infrared, 1H, 13C, and 31/sup

Synthesis of bis- and tris-organophosphorus substituted amines and amino acids with PCH2N Fragments

The aminomethylation of the derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde, and amines are thoroughly investigated via the treatment of reaction mixtures with bis(trimethylsilyl)amine.

NOVEL UNSYMMETRICAL N,N-BIS(METHYLENE)BIPHOSPHONIC ACIDS OF α,ω-DIAMINES. PREPARATION AND CHARACTERIZATION OF BIS(METHYLENE)>-BIPHOSPHONIC ACID AND BIS(METHYLENE)>-BIPHOSPHONIC ACID

Reaction of ethylenediamine with phosphorous acid and formaldehyde in molar ratio 1:2:2 gives bis(methylene)>biphosphonic acid (2a) as the major product.Similarly, reaction of hexamethylenediamine with phosphorous acid and formaldehyde in molar ratio 1:2:2 yields bis(methylene)>biphosphonic acid (2b) which is isolated either as bis(methylene>biphosphonic acid (3b) or as bis(methylene)>biphosphonic acid (4b).Removal of the carbobenzoxy group with HBr 3b or the benzoyl group with HCl from 4b gives pure bis(methylene)>biphosphonic acid (2b).All compounds were characterized by 13C NMR, 31P NMR and elemental analysis.
