摘要

Ce[N(SiMe3)2]3(THF)3应读作Ce[N(SiMe3)2]3。根据校正后的辅助资料中提供的分析数据和分子结构,没有与铈中心协调的THF。也重复了化学计量反应(方案9),并在修正的支持信息中提供了修订的光谱。所有的催化反应都按照前一篇文章中提到的摩尔%计算,用Ce[N(SiMe3)2]3重复,产率没有明显变化。下面的文字应该添加到13583页实验机理方面的副标题下:“该混合物的1H NMR谱是不确定的,但在Ce[N(SiMe3)2]3与苯酰胺1:1混合物的质谱中观察到581.6802处的小峰,对应于单酰胺铈络合物。”下面的文字应该在13583页的实验力学方面的副标题下添加:“质谱数据显示在m/z 501.1758处有一个强烈的峰,这与苯酰胺的三胺酸铈配合物的质量很好地匹配(图S51)。”方案6的脚注中应添加以下文字:在内标(三聚甲苯)存在下,通过积分1H NMR谱来确定产率。催化剂(1mol %)反应时间为24h,反应时间为4h。d2b、2d和2g需要高温(~ 100℃)和24小时的反应时间。方案7的脚注中应添加以下文字:在内标(三聚甲苯)存在下,通过积分1H NMR谱来确定产率。b2j和2n需要高温(~ 100℃)和24小时的反应时间。支持信息可在https://pubs.acs.org/doi/10.1021/acscatal.5c02346免费获取。实验程序和表征数据,动力学研究,核磁共振光谱(1H NMR, 13C NMR, 29Si NMR和11B NMR),质谱和拉曼光谱(PDF)更正“在温和条件下用Ce[N(SiMe3)2]3(THF)3脱氧1°和2°酰胺”4次查看0次分享0次下载大多数电子支持信息文件可在不订阅ACS Web版本的情况下获得。这些文件可以通过文章下载用于研究用途(如果相关文章有公共使用许可链接,该许可可以允许其他用途)。如有其他用途,可通过RightsLink权限系统http://pubs.acs.org/page/copyright/permissions.html向ACS申请。这篇文章尚未被其他出版物引用。

Correction to “Deoxygenation of 1° and 2° Amides with Ce[N(SiMe3)2]3(THF)3 under Mild Conditions”
The Ce[N(SiMe3)2]3(THF)3 should be read as Ce[N(SiMe3)2]3 in this work. There is no THF coordinated with the cerium center as per the analytical data and the molecular structure provided in the corrected Supporting Information. The stoichiometric reactions (Scheme 9) are also repeated, and revised spectra are provided in the corrected Supporting Information. All the catalytic reactions are repeated with the Ce[N(SiMe3)2]3 as per the mol % calculation mentioned in the previous submission, and there is no significant change in the yields. The following text should be added on page 13583 under the subheading of EXPERIMENTAL MECHANISTIC ASPECTS: “The 1H NMR spectrum of this mixture was inconclusive, but a small peak at 581.6802 was observed in the mass spectrum of a 1:1 mixture of Ce[N(SiMe3)2]3 with benzamide, which corresponds to the cerium mono-amidate complex.” The following text should be added on page 13583 under the subheading of EXPERIMENTAL MECHANISTIC ASPECTS: “The mass spectrometric data showed an intense peak at m/z 501.1758, which matches well with the mass of the cerium tris-amidate complex of benzamide (Figure S51).” The following text should be added in the footnote of Scheme 6: aYields were determined by integrating 1H NMR spectra in the presence of an internal standard (mesitylene). bReaction time of 24 h. cCatalyst (1 mol %) and 4 h reaction time. d2b, 2d , and 2g require high temperature (∼100 °C) and 24 h reaction time. The following text should be added in the footnote of Scheme 7: aYields were determined by integrating 1H NMR spectra in the presence of an internal standard (mesitylene). b2j and 2n require high temperature (∼100 °C) and 24 h reaction time.
