An Efficient One Pot Procedure for Preparation of Symmetrical N,N'-Disubstituted Urea from Aromatic and Aliphatic Amines and Urea under Microwave Irradiation
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.
متن کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
متن کاملN uptake and yield of wheat as influenced by integrated use of organic and mineral nitrogen
The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...
متن کاملUptake and distribution of N-phosphonomethylglycine in sugar beet plants.
Glyphosate (N-phosphonomethylglycine) was readily transported in sugar beet plants (Beta vulgaris L., Klein E type, monogerm). Concentrations in sink leaves reached 2.5 to 13.7 micromolar in 10 hours from a 15 millimolar solution supplied to one mature leaf. Distribution of glyphosate followed that of [(3)H]sucrose used as a marker for materials transported by phloem, indicating that this is th...
متن کاملUrea–N,N-dimethylacetamide (1/1)
Urea forms a 1:1 solvate with N,N-dimethyl-acetamide (DMA) [systematic name: diamino-methanal-N,N-dimethyl-acetamide (1/1), C(4)H(9)NO·CH(4)N(2)O] with both mol-ecules positioned on a twofold axis, giving rise to rotational disorder of the DMA mol-ecule. The mol-ecules display a layered structure in which urea mol-ecules form hydrogen-bonded ribbons bounded by mol-ecules of solvent.
