- Volatiles from the Psychrotolerant Bacterium Chryseobacterium polytrichastri
-
The flavobacterium Chryseobacterium polytrichastri was investigated for its volatile profile by use of a closed-loop stripping apparatus (CLSA) and subsequent GC-MS analysis. The analyses revealed a rich headspace extract with 71 identified compounds. Compound identification was based on a comparison to library mass spectra for known compounds and on a synthesis of authentic standards for unknowns. Important classes were phenylethyl amides and a series of corresponding imines and pyrroles.

- Improving C=N bond reductions with (Cyclopentadienone)iron complexes: Scope and limitations
-
Herein, we broaden the application scope of (cyclo-pentadienone)iron complexes 1 in C=N bond reduction. The catalytic scope of pre-catalyst 1b, which is more active than the “Kn?lker complex” (1a) and other members of its family, has been expanded to the catalytic transfer hydrogenation (CTH) of a wider range of aldimines and ketimines, either pre-isolated or generated in situ. The kinetics of 1b-promoted CTH of ketimine S1 were assessed, showing a pseudo-first order profile, with TOF = 6.07 h–1 at 50 % conversion. Moreover, the chiral complex 1c and its analog 1d were employed in the enantioselective reduction of ketimines and reductive amination of ketones, giving fair to good yields and moderate enantioselectivity.

- Synthesis and spectral studies on Pb(II) dithiocarbamate complexes containing benzyl and furfuryl groups and their use as precursors for PbS nanoparticles
-
Nine lead bis(dithiocarbamate) complexes based on benzyl and furfuryl groups have been prepared. The complexes were characterized using IR and NMR spectroscopy. All the complexes showed the expected signals in 1H and 13C NMR spectra associated with the dithiocarbamate ligands. IR and 13C NMR spectral studies indicate that the S2CN double bond character increases with increase in length of alkyl chain bonded to nitrogen atom. Bis(N-benzyl-N-(2-phenylethyl)dithiocarbamato-S,S′)lead(II) (3) and bis(N-furfuryl-N-(2-phenylethyl)dithiocarbamato-S,S′)lead(II) (4) have been used as single source precursors for the synthesis of ethylenediamine capped PbS nanoparticles. Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), FTIR, UV-vis and fluorescence spectroscopy have been used to characterize the as-prepared lead sulfide nanoparticles. The PXRD measurements suggest that PbS nanoparticles are single phase with face-centered-cubic structure.

- Molecular sieves in ionic liquids as an efficient and recyclable medium for the synthesis of imines
-
A great variety of imines were efficiently isolated in high yields from the reaction of aldehydes and amines in ionic liquids. The ionic liquids could be recovered and reused for at least five cycles without loss in the yields being a useful alternative to dichloromethane or diethyl ether, which are the commonly used solvents for this reaction.

- Preparation of Secondary Amines and β-Amino esters via Additions of Grignard and Reformatsky Reagents to Imines and by One-Pot Reactions of Primary Amines, Aldehydes, and Grignards
-
Additions of Grignard and Reformatsky reagents to imines in the presence of 1-(trimethylsilyl)benzotriazole afforded in good yields the corresponding secondary amines and β-amino esters.The procedure is general as imines containing hydrogens α to both carbon and nitrogen can be employed.Extensions of this method to include imines containing other Lewis basic centers, e.g., those derived from furan-, thiophene-, indole-, and p-methoxybenzenecarboxaldehyde, have been successful in avoiding the potential complications which could result from the use of a Lewis acid as the activating species.The imines need not be isolated, and a one-pot method for the synthesis of secondary amines from aldehydes, primary amines, and Grignard reagents is described.
