Bis benzonitrile dichloropalladium

Bis(benzonitrile)dichloropalladium is a yellow-orange solid that is soluble in benzene, chloroform, and dichloromethane, but insoluble in water, alcohols, and diethyl ether. The IR spectrum (KBr pellet) exhibits CsN stretching vibrations at 2235 and 2290 cm. The H NMR spectrum (CDCI3) contains 

The following procedures for the preparation of bis(benzonitrile) dichloropalladium and -platinum involve slight modifications of the methods reported previously. Palladium(II) chloride and platinum(II) chloride were provided by Johnson Matthey. Benzonitrile was distilled immediately prior to use.

Carboxyethylthio aryl tellurium compounds displaced benzonitrile in bis[benzonitrile] dichloropalladium(II)5. 

Phenyl triphenylgermyl or triphenylstannyl tellurium transferred the benzenetellurolate group to palladium in a reaction with bis[benzonitrile]dichloropalladium(II)1. 

When benzoyl aryl tellurium and bis[benzonitrile]dichloropalladium were stirred in chloroform, polymeric bis[aryllellurolato]palladium compounds were isolated. The benzoyl group was cleaved from the tellurium atoms during these reactions. 

The formation of (l,5-hexadiene)dichloropalladium(II) by reaction of dry allyl chloride with bis(benzonitrile)dichloropalladium(II) at about 5°C has been reported (627). X-Ray analysis has shown the molecule to have the structure (200) in which carbon atoms C-1-C-2-C-3 and C-4-C-5-C-6 are in mutually perpendicular planes both of which are... 

Rearrangement of cis,reaction with bis(benzonitrile)dichloropalladium(II) in benzene has also been reported (581). The product is (m-l,2-divinylcyclohexane)dichloro-palladium(II), a monomeric complex decomposing above 123°C. The... 

Interaction of bis(benzonitrile)dichloropalladium(II) with all-trans-and cis,trows,melting with decomposition at 170° and 190°C, respectively. The infrared spectra of the complexes indicate that coordination is at a trans double bond in both species. 

The reaction of 13x with bis(benzonitrile)dichloropalladium(II) [Bn2PdCl2[ and monochloro(l,5-cyclooctadiene)monomethylpalladium(ll) [(COD)PdCIMe] yielded the corresponding palladium(II) complexes 14x and 15x (Fig. 2.16). Upon slow evaporation of an acetonitrile solution, 14 c and 14 d gave crystals that were suitable for structure determination via single crystal X-ray diffraction (Fig. 2.17). Compound 14 b was crystallized by slow diffusion of pentane into a solution of 14b in tetrachloroethane. 

Bis(benzonitrile)dichloropalladium(II)18 (3.00 g., 7.8 mmoles) is dissolved in a mixture of 40 ml. of water and 60 ml. of acetone. trans, trans-2,4-Hexadiene (3.5 ml., 35 mmole) is added. After 10 minutes the solution is extracted with dichloromethane, and the extract is washed with water and dried over Na2S04. After evaporation to dryness, the residue is dissolved in a small amount (5-10 ml.) of CH2C12 and filtered. The filtrate is diluted with pentane until the solution becomes turbid and a precipitate appears. In addition, the solution is cooled to —80°. Filtration through a sintered-glass filter and drying under vacuum gives 1.5 g. (80% theoretical) of the title compound.
