  Limitations in advance task preparation: Switching the relevant stimulus dimension in speeded same—different comparisons

  摘要：

  When participants switch between relevant stimulus dimensions in speeded classification tasks, task-switching cost is reduced by advance preparation. Previous studies in which speeded classification tasks were used have suggested that this effect results from attending to the relevant stimulus dimension. Because selective attention to the relevant stimulus dimension in same-different judgments is relatively poor (e.g., Santee & Egeth, 1980), it was predicted that advance task preparation for a shift in the relevant stimulus dimension would be compromised. This prediction was borne out in two experiments comparing dimension shifts (skape vs. fill) with task rule shifts (same? vs. different?) and shifts in the mapping of right-left keys to yes and no responses (yes-no vs. no-yes). The results indicate that advance attentional selection of the relevant dimension is an optional preparatory strategy in task switching, employed only in conditions enabling flexible refocusing of attention.

• Palladium(II)-Catalyzed Tandem Oxidative Acetoxylation/<i>ortho</i> C–H Activation/Carbocyclization of Arylallenes

  Herein we report an example of tandem oxidative acetoxylation/carbocyclization of arylallenes 1 using Pd(OAc)2. The catalytic protocol is highly selective and provides access to new C–C and C–O bonds leading to a carbocyclization. The reaction proceeds via C–H activation by Pd. Mechanistic investigations show that the C–H activation is not the rate-limiting step and indicate that the reaction proceeds

  在此，我们报告了使用 Pd(OAc)2 对芳基丙二烯 1 进行串联氧化乙酰氧基化/碳环化的例子。催化方案具有高度选择性，可提供导致碳环化的新 C-C 和 C-O 键。反应通过 Pd 的 C-H 活化进行。机理研究表明，C-H 活化不是限速步骤，表明反应是通过丙二烯的乙酰氧基化进行的。
