Abstract: The aryne and its intermediates or their precursors are the most important compounds in organic synthesis for the purpose of arynes or benzyne insertion in many reactions. Arynes are among the first reactive intermediates known to organic chemists. Since their discovery, they have fascinated chemists from both theoretical and synthetic perspectives... Show More

Abstract: Neutron activation analysis followed by a gamma-ray spectroscopy and physico-chemical methods were used to conduct a thorough investigation of the elements transferred from sewage sludge (biosolid) into the wood of Eucalyptus grandis. Four different manure samples were analyzed: control without biosolid and samples with 10, 20 and 40 t ha^-1 of bios... Show More
