Phospholes.2 Reduction of zirconocene dichloride (1) by BuLi in the presence of 2-butyne provides the zirconium metallacycle 2, which can be isolated if desired as air-sensitive, orange-red crystals in 85% yield. Reaction of 2 with dichlorophenyl-phosphine provides the phosphole 3 (l-phenyl-2,3,4,5-tetramethylphosphole). The intermediate 2 can also be converted into arsoles, stiboles, bismoles, siloles, ger-moles, stannoles, thiophenes, and selenophenes by the use of appropriate organome-tallics. 

One interesting application of an ionic liquid does not involve its use as a solvent. The company BASF used N-methylimidazole to scavenge the HC1 formed in the reaction of dichlorophenyl phosphine with ethanol (Fig. 7.33). This results in the formation of N-methylimidazoliumchloride (Hmim-Cl), which has a... 

Photocatalytic reductions may concern organic unsaturations (C=0, C=C, etc.), or inorganic CO2, or bicarbonate. Even carbon tetrachloride is very efficiently photo-reduced to chloroform by alcohols with mc.9o-tetra(2,6-dichlorophenyl)porphyrin [108]. Intermolecular hydrogen transfer is catalyzed by cobalt-phosphine complexes [109]. In this reaction photoirradiation generates the active hydride species CoH[PPh(OEt)2]3 for the reduction of ketones with secondary alcohols. The... 

A new synthetic approach to lamotrigine has recently been suggested <2005RCB726>. It is based on the coupling of tetrazolyldiazonium salts with a-formyl-a-(2,3-dichlorophenyl)acetonitrile followed by treatment of the corresponding tetrazolo[4,5- ][l,2,4]triazine with triphenyl phosphine (Scheme 195) <2005RCB726>. 

A single short H bond links two phosphine oxide molecules in (Ph3PO)2H+ AuClj (13.34a) and two acid phosphate ions in KH5(P04)2 (13.34b). Continuous chains are formed in p-dichlorophenyl phosphate (13.34c), dimer rings in dibenzyl phosphoric acid (13.34d) and rings in the ruthenium complex (13.34e).

The titanacyclopentadiene-containing polymers (22) can be converted into Jt-conjugated phosphole-containing polymers (28) by the reaction with dichlorophenyl-phosphine (scheme 16). Similar to the case of the above-mentioned conversion reaction into thiophene-containing polymers, the produced polymers are partially... 

The phosphorous derivative 16 was prepared by reaction of lithium diphenyl phosphide with PEG bromide, and the related derivative 18 was prepared by reaction of PEG itself with dichlorophenyl phosphine. Derivatives 16 and 1 were used to prepare the polymer-bound rhodium compounds 17 and 1, respectively. These rhodium complexes were of interest as water-soluble, recoverable catalysts. Whitesides and coworkers have prepared a rhodium derivative similar to 17 using PEG with molecular weight of approximately 1000 g/mol. We found the products derived from such low molecular weight PEG s to be amorphous and less readily recoverable (by precipitation) in comparison to our higher molecular weight (6800 g/mol) derivatives. Catalytic studies of 17 and are in progress.
