  Recognition memory for source and occurrence: The importance of recollection

  摘要：

  Previous recognition memory studies indicate that when both recollection and familiarity are expected to contribute to recognition performance (e.g., discriminating studied items from nonstudied items) the dual-process and the unequal-variance signal detection models provide comparable accounts of performance. When familiarity is not expected to be useful (e.g., when items from two equally familiar sources are discriminated between), the dual-process model provides a significantly better account of performance. In the present study, source recognition was tested under conditions in which familiarity could have been used to perform a list-discrimination task; participants were required to discriminate between strong studied items, weak studied items, and new items., The dual-process model provided a better account of performance than did the unequal-variance model. Moreover, the results indicated that the unequal-variance assumption in a single-process signal detection model was not a valid substitution for recollection and that recollection was used to make recognition judgments even when assessments of familiarity were useful.

  水杨醛与重氮化合物之间可控的Rh（III）催化环空：色酮和苯并呋喃的不同合成

  摘要：

  描述了Rh（III）催化的水杨醛和重氮化合物之间具有可控的化学选择性的环化反应。AgNTf 2通过串联的C–H活化/脱羰/环化过程有利于苯并呋喃，而AcOH通过C–H活化/环化途径生成色酮。该反应表现出良好的官能团耐受性和可扩展性。此外，由于原位脱羰取向作用，仅获得了单一的苯并呋喃的区域异构体。

  A Rh(III)-catalyzed annulation between salicylaldehydes and diazo compounds with controllable chemoselectivity is described. AgNTf2 favored benzofurans via a tandem C–H activation/decarbonylation/annulation process, while AcOH led to chromones through a C–H activation/annulation pathway. The reaction exhibited good functional group tolerance and scalability. Moreover, only a single regioisomer of benzofuran

  Recently, N-hydroxyindole derivatives have received much interest because of their unique structural motif and various biological activities. In this study, we report the first example of a Rh(III)-catalyzed reaction of arylnitrones with α-diazoketoesters or α-diazodiketones to produce N-hydroxyindole derivatives. Intriguingly, we could build the N-hydroxyindole scaffold by blocking the cleavage of

  Chemodivergent coupling of α-acylketene dithioacetals with diazo compounds has been realized under catalyst control. The Ru(II)-catalyzed C–H activation occurred at the olefinic position, and 1:2 coupling with α-diazoketoesters leads to furfurylation. In contrast, the Rh(III)-catalyzed C–H functionalization occurred at both the olefinic and the ortho C(aryl)–H positions, and [4 + 2] annulation afforded
