Two molar amounts of arynes were found to insert into a Sn-Sn bond of a distannane in the presence of a sub-stoichiometric amount of a palladium-phosphite complex, affording straightforwardly 2,2'-distannylbiaryls.

In the title compound, C(4)H(12)N(+)·H(2)PO(3) (-), the components are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, resulting in a two-dimensional framework.

The asymmetric unit of the title triangulo-triruthenium compound, Ru(3)(CO)(9)(μ-Ph(2)AsCH(2)AsPh(2))(P[OCH(CH(3))(2)](3)) or [Ru(3)(C(25)H(22)As(2))(C(9)H(21)O(3)P)(CO)(9)], contains two mol-ecules of the triangulo-triruthenium complex. The bis-(diphenyl-arsanyl)methane ligand bridges an Ru-Ru bond and the monodentate phosphite ligand binds to the third Ru atom. Both the arsine and phosphite l...

Pentacoordinated iridium(i) complexes of formula IrCl(SiNP)(tfbb) (1) and IrCl(HNP)2(tfbb) (2) (SiNP = SiMe2{N(4-C6H4CH3)PPh2}2; HNP = NH(4-C6H4CH3)PPh2) have been prepared and fully characterised. Both feature a distorted square pyramidal coordination polyhedron at the metal centre in the solid state and are fluxional in solution. Their reaction with trimethyl phosphite yields the derivatives ...

Ethanol production from corn starch in the corn dry milling process leaves Distillers' Dry Grains and Solubles (DDGS) as a major by-product from which additional ethanol may be economically obtained from its glucan content. A challenge in processing the cellulose content of this material lies in its extensive inter-cellulose chain hydrogen bonding, which inhibits access of enzymes capable of cl...

The application as soil drenches of three commercial products containing metalaxyl, phosphorous acid or potassium silicate, were studied a means controlling Phytophthora in chestnut (Castanea sativa Mill.) seedlings. In the metalaxyl treatment no plant deaths recorded, whereas with and silicate applications, untreated control, mortality rate was respectively 33.3, 44.4 77.8%. presence detected ...

Substituted 3-(fluoroacyloxy)quinoline-2,4(1H,3H)-diones including 3-(fluoroiodoacetoxy) derivatives react with triethyl phosphite to afford either the product of the Perkow reaction or the corresponding 4-ethoxyquinolin-2(1H)-one. In both reactions, the fluorocarboxylate anion acts as the first observed leaving group. This observation restricts the application of the intramolecular Horner-Wads...

The title compound, C17H27O8P, was prepared by Michaelis-Arbuzov reaction of ethyl 2-bromo-2-(2,3,4-tri-meth-oxy-phen-yl)acetate and triethyl phosphite. Such compounds rarely crystallize, but single crystals were recovered after the initial oil was left for approximately 10 years. The bond angle of the sp (3)-hybridized C atom connecting the benzene derivative with the phospho unit is widened m...

A new zinc phosphite exhibited remarkable structural transformations upon heat stimulation to convert into a dehydrated form (NCU-2a) and a new structure, NCU-2b. The gas adsorption properties of the materials as well as the luminescence properties of LED devices fabricated using these materials were also investigated.
