In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)]·0.5C(3)H(6)O, the Rh atom exhibits a square-planar coordination geometry, being coordinated by the N and O atoms of the bidentate β-diketonato ligand, a P atom from the triphenyl-phosphine unit and a C atom from the carbonyl group. The asymmetric unit also contains a disordered half-mol-ecule, lying about an inversion center, of the ace...

The title compound, C(44)H(35)NS, is a derivative of amino-thio-phenol and possesses a protected S-triphenyl-methyl thio-ether and an N-triphenyl-methyl-amine functional group. The trityl groups show an anti orientation, with C-C-N-C and C-C-S-C torsion angles of -151.0 (3) and -105.3 (2)°, respectively. There is an intra-molecular N-H⋯S hydrogen bond.

Cold-acclimated twigs of Amelanchier alnifolia Nutt. released less HCN at -4.5 C than nonacclimated twigs following slow freezing to -25 C or rapid freezing to -78 C. Cold-acclimated twigs frozen slowly to -25 C released more HCN than cold-acclimated twigs frozen only to -4.5 C. Cold-acclimated twigs frozen slowly to -25 C and then rapidly to -78 C released less HCN at -4.5 C than cold-acclimat...

We report the first comprehensive insecticide susceptibility status ofAedes aegypti (L.) larvae from Singapore. The study indicated that Ae. aegypti is susceptible to temephos, although resistance (RR50 = 1.29-4.43-fold) couldbe developing. Of high concern is the detection of moderate to high resistance to permethrin (RR50 = 29-47-fold) and etofenprox (RR50 = 14-34-fold). Biolarvicide Bacillus ...

Concern has mounted over health effects caused by exposure to flame retardant additives used in consumer products. Significant research efforts have focused particularly on exposure to polybrominated diphenyl ethers (PBDEs) used in furniture and electronic applications. However, little attention has focused on applications in textiles, particularly textiles meeting a flammability standard known...

1H NMR spectroscopy and chemometric analysis were used to characterize rat urine obtained after chronic exposure to either tributyl phosphate (TBP) or triphenyl phosphate (TPP). In this study, the daily dose exposure was 1.5 mg/kg body weight for TBP, or 2.0 mg/kg body weight for TPP, administered over a 15-week period. Orthogonal signal correction (OSC) -filtered partial least square discrimin...
