The site has three main habitats along a permafrost thaw gradient, with distinct vegetation and thaw status: (1) palsa, overlaying permafrost, well-drained and dominated by woody plants and shrubs; (2) bog, intermediate thaw with variable water table depth characterized by a mixture of woody,...
Cyclization of 562 in the presence of a base (lithium hexamethyldisilazide (LiHMDS), THF, −78 °C) or a Lewis acid (n-Bu2SnO in refluxing benzene) afforded a mixture of isoxazolidinones 563 and 564 in high yield but with little diastereoselectivity (Scheme 136). Diastereomers 563 ...
lead ingot may be used to manufacture a new battery grid, or it may be oxidised using a Barton pot or ball-mill process to produce leady oxide, typically a mixture of lead oxide and free metallic lead. This leady oxide may then be reused as the active, redox material in lead-acid batt...
