A variety of aldehydes react with acetic anhydride in the presence of a catalytic amount of H2SO4-silica to afford the corresponding 1,1-diacetates (acylals) in excellent yields. Ketones are not affec...
The reactions of Cl atoms with a series of unsaturated aldehydes have been investigated for the first time using a relative method. In order to obtain additional information for a qualitative structur...
We describe measurements of total peroxy nitrates (ΣPNs), NO2, O3 and several aldehydes at Granite Bay, California, during the Chemistry and Transport of the Sacramento Urban Plume-2001 (CATSUP 2001) ...
We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
摘要 A combination of sodium borohydride and a catalytic amount of indium(III) chloride in acetonitrile reduces imines formed in-situ from aldehydes and amines to the corresponding functionalised second...
专著信息 书名 3,3‘-Functionalized octahydro-BINOL: a facile synthesis and itshigh enantioselectivity in the alkyne addition to aldehydes, 语种 英文 撰写或编译 作者 Lan Liu,Lin Pu 第一作者单位 出版社 Tetrahedron 60 (2004) 7427–...
Like marine diatoms, some freshwater diatoms produce α, β, γ, δ-polyunsaturated aldehydes (PUA) when damaged. Some of these oxylipins are suspected of impairing egg viability in marine copepods. To de...
Aldehydes and ketones react with tribromonitromethane in the presence of zinc metal dust, ammonium chloride and water to give dibromonitroalcohols in good yields.
