标题:监管焦点在创造力中的激励作用
摘要:监管焦点理论认为,人们在追求目标时可能会专注于实现积极的结果(有促进焦点)或避免消极的结果(有预防焦点).在促进焦点下,人们会制定尽可能多的策略来实现他们的目标,从而在他们执行创造性任务时能够流畅地产生想法.相比之下,处于预防重点的人会寻求避免未能实现有价值目标的负面后果,即使在创造力情况下成功的可能性很小,他们也会坚持下去.我们在一项研究中测试了这些预测,其中监管焦点被测量为个体差异变量(第 1 部分)并由目标框架操纵(第 2 部分)诱导.结果支持了我们的预测,

标题:Process for preparation of 1,4-haloallylic esters from dienes
发明人:CARDENAS CARLOS G
权利人:SCM CORP
摘要:A process for the synthesis of 1,4-haloallylic esters from conjugated dienes which comprises preparing a reaction mixture of the conjugated diene, a halogenating agent, and a carboxylic acid and then adding to said reaction mixture a catalytic amount of a strong acid having a high dissociation constant. The invention is particularly described with reference to the synthesis of isoprene-1,4-chloroacetate(1-chloro-4-acetoxy-2-methyl-2-butene) from isoprene wherein a reaction mixture is prepared of isoprene with t-butyl hypochlorite in excess glacial acetic acid, to which is added H2SO4 followed by stirring at 50 DEG C.

标题:Optically isomeric inositol and process for making optically active compound

摘要:Optically active diols and hydroxycarboxylic acids and their esters are produced by deriving 1L-1,2:5,6-di-O-cyclohexylidene-chiro-inositol from 1L-chiro-inositol as an asymmetric source, followed by introduction of a selected class of sterically hindering and asymmetrically reactive groups into the first-mentioned compound and by subsequent reduction of the resulting compound. Seven specific inositols are also derivable from synthesis of those ultimate compounds.

标题 :Process for chemical synthesis from an alkenone made from a halogenated precursor

权利人:BRAUN MAX; PALSHERM STEFAN; CLAASSEN UTA; LAMBERT ALAIN; SOLVAY
摘要:Process for synthesizing a chemical, in particular an agriculturally or pharmaceutically active compound, including: a first step comprising reacting a carboxylic acid halide with a vinyl ether to prepare a halogenated precursor of an alkenone; a second step comprising eliminating hydrogen halide from such precursor to form an alkenone, preferably by thermolysis under specific conditions; and a third step which uses the formed alkenone as a building block to synthesize the chemical. First step may be done in a liquid reaction medium comprising an alkenone or a halogenated alkenone precursor, or in a liquid reaction medium in turbulent state, specifically by creation of gas bubbles of the carboxylic acid halide herein. Second step may include a flash thermolysis, vacuum thermolysis, thermolysis under stripping with inert gas, and/or a thermolysis at a temperature from >90° C. to 120° C. Third step preferably comprises reacting the alkenone with a nitrogen-containing compound.
