The sodium salt of the optically active tetrakis(4,5,6,7-tetrahydro-7,8,8-trimethyl-2//-4,7 methanoindazolyl)borate, Na(pz-jpcamph-j was preparecl by the reaction of 4,5,6,7-tetrahydro-7, 8,8-trimethyl-2//-4,7-methanoindazole with NaBFLp Analogously the sodium salt of hydrotris((—)-3(5)-methyl-l-phenylethy-... 

This complex is not the actual catalyst for the hydrovinylation, but needs to be activated in the presence of a suitable co-catalyst. The role of this additive is to abstract the chloride ion from the nickel centre to generate a cationic allyl complex that further converts to the catalytically active nickel hydride species. In conventional solvents this is typically achieved using strong Lewis acids such as Et2AlCl. Alternatively, sodium or lithium salts of non-coordinating anions such as tetrakis-[3,5-bis(trifluoromethyl)phenyl]borate (BARF) can be used to activate hydrovinylation... 

Quantitative risk assessments have been performed on a variety of flame-retardants used both in upholstered furniture fabric and foam. The National Research Council performed a quantitative risk assessment on 16 chemicals (or chemical classes) identified by the U.S. Consumer Product Safety Commission (CPSC). The results were published in 2000.88 The 16 flame-retardants included in this NRC study were HBCD, deca-BDE, alumina trihydrate, magnesium hydroxide, zinc borate, calcium and zinc molybdates, antimony trioxide, antimony pentoxide and sodium antimonate, ammonium polyphosphates, phosphonic acid, (3- [hydroxymethyl]amino -3-oxopropyl)-dimethylester, organic phosphonates, tris (monochloropropyl) phosphate, tris (l,3-dichloropropyl-2) phosphate, aromatic phosphate plasticisers, tetrakis (hydroxymethyl) hydronium salts, and chlorinated paraffins. The conclusions of the assessment was that the following flame-retardants can be used on residential furniture with minimal risk, even under worst-case assumptions ... 

A complementary, but less pronounced, increase in cis syri) selectivity is provided when diazoacetates with rather small ester groups and rhodium catalysts with bulky ligands, such as iodorhodium(IIl) porphyrins and mcso-tetrakis(2,4,6-triarylbenzoato)di-rhodium(ll) complexes, are employed. For ethyl 2-alkylcyclopropane-l-carboxylates so obtained, a cisfran.s ratio of 2-4 was typical. Notable cis selectivities have also been achieved in the synthesis of ethyl 2-phenylcyclopropane-l-carboxylate with the catalyst [(r/ -C5H5)Fe(CO)2(THF)][BFJ (cis/trans 5.25, see Section 1.2.1.2.4.2.6.3.1.) and copper catalysts prepared in situ from a copper salt [copper(I) iodide, copper(II) acetate or triflate] and sodium tetrakis(7,8,8-trimethyl-4,5,6,7-tetrahydro-2Ff-4,7-methanoindazolyl)borate (3) cis/ trans 2.1-3.2). °... 

Recently, interesting recognition abilities toward both sodium and potassium cations were reported for cone-shaped l,4 2,3-doubly-bridged calrx[7]arene 8i [6b] by using the corresponding Tetrakis[3,5-bis(triFluoromethyl)Phenyl]Borate (TFPB ) salts. In particular, a selectivity of 94 for sodium over potassium was found [6b]. Derivative 8i also showed interesting recognition abilities toward linear and branched alkyl ammonium cations with which forms cnt/o-cavity complexes (Fig. 7.19). 

Barlow et al. reported the synthesis of cationic (T) -cyclopentadienyl)(r -fulvene)ruthenium(ll) salts from ruthenocenylmethanol (57) either by treatment with trimethylsilyl triflate to achieve 58 in 79% yield. Alternatively, the reaction of 57 with tetrafluoroboric acid or with hexafluorophosphoric acid gave the tetrafluoroborate or hexafluorophosphate salts in 59 and 60 in 92% and 52% yield, respectively. Treatment of 59 with sodium tetrakis[3,5-bis(trifluoromethyl)]borate afforded the tetraarylborate salt 61 in 69% yield. 

Poly(vinyl chloride) (PVC) with an average polymerization degree of 1100 was purified by reprecipitation from THF in methanol. The plasticizers or membrane solvents, di-n-octylphthalate (DOP), o-nitrophenyl octyl ether (NPOE), and 2-fluorophenyl-2-nitrophenyl ether (FPNPE) were obtained from Dojindo Laboratories. The lipophilic salt, sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaTFPB), was obtained from Tokyo Chemical Industry Co., Ltd. and Dojindo Laboratories.
