ISSN: 1387-7003. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 29, 75 The new dihydrobis(3-carboxyethyl-5-methylpyrazolyl)borate ligand BpCOOET,Me was prepd. as its K salt in kerosene soln., using Et 3-methylpyrazole-5-carboxylate and KBH4, through careful temp. 4027-57-0 and 830320-09-7 which are cas registry numbers of chemicals are mentioned. control. BpCOOET,Me reacts with CuCl and PPh3 to yield the {Cu(BpCOOET,Me)PPh3} complex. BpCOOET,Me and {Cu(BpCOOET,Me)PPh3} were fully characterized by elemental analyses and FTIR in the solid state and by NMR (1H, 13C and 31P) spectroscopy and electrospray ionization mass spectrometry in soln. A single crystal structural characterization is reported for {Cu(BpCOOET,Me)PPh3}. .

Santini, Carlo (Dipartimento di Scienze Chimiche, Universita degli Studi di Camerino, Camerino, MC 62032, Italy). Inorganic Chemistry Communications, 7(7), 834-837 (English) 2004 Elsevier Science B.V. CODEN: ICCOFP. ISSN: 1387-7003. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 28 The new [(3-carboxy-5-methyl-1H-1-pyrazolyl)(3-methyl-5-carboxy-1H-1-pyrazolyl )methane], CH2(PzCOOH,Me)(PzMe,COOH), and bis(3-carboxy-5-methyl-1H-1-pyrazolyl)methane, CH2(PzCOOH,Me)2, ligands were prepd. in CH2Cl2/water soln. using Et 3-methylpyrazole-5-carboxylate, an excess of Na2CO3, and benzyltriethylammonium chloride as the phase transfer catalyst. The CH2(PzCOOH,Me)2 ligand reacts with ZnAc2 and CdCl2 in the presence of two equiv of NaOH to yield {M[CH2(PzCOOH,Me)2](H2O)n} (M = Zn(II), n = 2; M = Cd(II), n = 1) complexes. All compds. were fully characterized by elemental analyses and FTIR in the solid state and by NMR (1H, 13C, and 113Cd) spectroscopy and electrospray ionization mass spectrometry in soln. The complexes likely contain a five- or six-coordinate metal core in which the ligand is coordinated to the metal ions in the k4-N,N',O,O' fashion. 4027-57-0 is just another one chemical used in this study. .
