In the title compound, [Fe(2)(C(7)H(4)IN)(C(3)H(6)S(2))(CO)(5)], the Fe-Fe distance of 2.5156 (11) Å compares well with that in related model structures. The phenyl isocyanide ligand is in the basal position and trans to the S atoms of the propane-dithiol-ate ligand due to steric hindrance. The crystal structure features C-H⋯O inter-actions.

Tungsten complex with a coordinated 2-azidoethyl isocyanide ligand reacts with PMe3 at the azido function to give a complex with a coordinated iminophosphorane which upon hydrolysis of the P=N bond yields a complex with an NH,NH-stabilized N-heterocyclic carbene ligand, 7; alkylation of the carbene ring nitrogen atoms gives a complex with an N,N'-dialkylated imidazolidin-2-ylidene ligand, 8 .

In the title compound, [FeBr(C9H9NO2S)(C30H30N2P2)][B(C6H5)4], the Fe(II) ion is in a distorted octa-hedral CBrN2P2 coordination geometry with a P-Fe-P angle of 109.95 (3)°. The relative orientation of the p-toluene-sulfonyl-methyl isocyanide ligand is defined by the C-S-C-N torsion angle of 67.1 (2)°. In the crystal, pairs of weak C-H⋯O hydrogen bonds connect the cations into inversion dimers,...

A simple and efficient strategy for the synthesis of indane-1,3-dione derivatives through a palladium(0)-catalyzed reaction incorporating tert-butyl isocyanide has been developed. In addition, by applying this protocol as the key step, indenopyrazole derivatives can be easily synthesized in high yields in a one-pot procedure. This methodology is tolerant of a wide range of substrates and applic...

The addition of 2,6-dimethylphenyl isocyanide (CN[DMeP], two equivalents) to previously reported (PNP)Sc(III) pyridyl complexes resulted in the formation of novel indoline complexes of scandium. By varying the nature of the pyridyl moiety one can intercept an intermediate prior to methyl migration. In addition to structural studies of two indolene complexes, we also propose a mechanism for the ...

A unique palladium-catalyzed arylation of alkyl sulfenate anions is introduced that affords aryl alkyl sulfoxides in high yields. Due to the base sensitivity of the starting sulfoxides, sulfenate anion intermediates, and alkyl aryl sulfoxide products, the use of a mild method to generate alkyl sulfenate anions was crucial to the success of this process. Thus, a fluoride triggered elimination st...

5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.

Multiple forms of liver microsomal cytochrome P-450 isolated from immature male rats pretreated with phenobarbital or 3-methylcholanthrene are described. A fraction. of low specific content (Fraction A, 1.7 to 4.0 nmol of cytochrome P-450 per mg of protein) and a fraction substantially purified (Fraction B, 9.0 to 11.0 mnol of cytochrome P-450 per mg of protein) are obtained by DEAE-cellulose c...

Treatment of pregnant rats with as little as 0.5 mg of BP per kg p.o. for 3 days stimulated the metabolism of the hydrocarbon by maternal liver and placenta, while a 20-fold higher dose of this hydrocarbon was necessary for stimulation of BP hydroxylation in fetal liver. BP metabolism was increased in fetal and maternal liver microsomes after treatment of pregnant rats with 3-methylcholanthrene...
