Following our previous paper, we exammed the effects on the heme synthesis in quail yolk sac cells of polar compounds, other than dimethyl sulfoxide. that induce erythroid cell differentiation in cultured Friend leukemia cells. Dissociated yolk sac cells from quail embryos at the definitive primitive streak stage were cultured in a gyratory shaker in a medium containing dimethyl sulfoxide or ot...

A phosgene-free synthesis of symmetrical N,N'-disubstituted urea by the reaction of aromatic and aliphatic primary amines and urea promoted by microwave irradiation in the presence of a suitable energy-transfer solvent such as N-N-dimethylacetamide is described.
In the title compound, C(6)H(5)IO(3)S·C(4)H(9)NO·H(2)O, N,N-dimethylacetamide and 4-iodobenzenesulfonic acidmolecules are linked by an intramolecular C-H⋯O hydrogen bond. In the crystal structure, inter-molecular O-H⋯O, O-H⋯I and C-H⋯O hydrogen bonds link the mol-ecules.
The PdCl(2)-promoted reactions of methylenecyclopropanes (MCPs) 1 bearing diaryl substituents on the terminal double bond were carefully investigated. The solvents employed significantly affected the reaction outcomes. It was found that dimeric allylpalladium(ii) complexes 2a-2f can be obtained as the sole products in acceptable to good yields under mild reaction conditions with THF as the solv...
The mononuclear complex (Bu4N)2[ReIVCl4(CN)2]·2DMA (DMA = N,N-dimethylacetamide) displays intricate magnetization dynamics, implying Orbach, direct, and Raman-type relaxation processes. The Orbach relaxation process is characterized by an energy barrier of 39 K (27 cm-1) that is discussed based on high-field electron paramagnetic resonance (EPR), inelastic neutron scattering and frequency-domai...
This article describes the development of a suitable Gel Permeation Chromatography method for cellulose nitrate plasticised with camphor (celluloid) found in cultural heritage. Current sample preparation and dissolution methods, apart from focusing on native, nonderivatised cellulose, require long times, often employ solvents that induce degradation. study aims to develop systematic uses least ...
