摘要

我们合成了分别含有叔胺奎宁环（1a-e）或 1,4-二氮杂双环[2.2.2]辛烷（DABCO；2a、2b 和 2e）的单羰基和双羰基次碘化物，它们代表了由烷基胺而不是芳香族路易斯碱（如吡啶衍生物）稳定的次碘化物的首个实例。通过 SCXRD 和 DFT 计算，对这些高活性复合物的固态特性进行了描述。DABCO 次碘酸根衍生物是罕见的二配位双（O-I-N）络合物，与 DABCO 以单配位方式配位的碘（I）络合物相比，DABCO 次碘酸根衍生物显示出意想不到的成键参数。我们合成了含有叔胺奎宁环或 1,4-二氮杂双环[2.2.2]辛烷的单羰基和双羰基次碘化物，它们是由烷基胺而不是芳香族路易斯碱稳定的次碘化物的首例。

Mono- and Bis-Carbonyl Hypoiodites of the Tertiary Amines Quinuclidine and DABCO

Mono- and bis-carbonyl hypoiodites incorporating the tertiary amines quinuclidine (1a–e) or 1,4-diazabicyclo[2.2.2]octane (DABCO; 2a, 2b, and 2e), respectively, have been synthesized and represent the first examples of hypoiodites stabilized by alkyl amines rather than aromatic Lewis bases (e.g., pyridine derivatives). These highly reactive complexes have been characterized in the solid state by SCXRD and DFT calculations. The DABCO hypoiodite derivatives are rare examples of ditopic bis(O–I–N) complexes and were found to display unexpected bonding parameters relative to iodine(I) complexes in which the DABCO is coordinating in a monotopic manner.

Mono- and bis-carbonyl hypoiodites incorporating the tertiary amines quinuclidine or 1,4-diazabicyclo[2.2.2]octane have been synthesized and represent the first examples of hypoiodites stabilized by alkyl amines rather than aromatic Lewis bases.

期刊介绍： The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials. Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
