  with [Fe2(CO)9] to afford the bis-μ-(S-alkyl)hexacarbonyldiiron coordination compounds: I (R1 = R2), II (R1R2 = bridging hydrocarbon chain) and III (R1 ≠ R2) after a double fragmentation pattern accompanied by loss of carbonyl groups. This unexpected reactivity of ligands IV offers a general route to binuclear iron compounds such as I and II. Some reaction intermediates [μ(RS)-μ-(RSCO)-Fe2(CO)6] (V)

  二硫代碳酸酯R 1 SC（O）SR 2（IV）与[Fe 2（CO）9 ]反应，得到双μ-（S-烷基）六羰基二铁配位化合物：I（R 1 = R 2），II（R 1 R 2 =桥接烃链）和III（R 1 ≠R 2）经过双断裂模式并伴有羰基的丢失。配体IV的这种出乎意料的反应性提供了通向双核铁化合物（例如I和II）的一般途径。一些反应中间体[μ（RS）-μ-（RSCO）-Fe 2（CO）6]（V）导致I，被识别。然而，在IV（R 1 ≠R 2）络合过程中发生的S-烷基基团的重新分布表明脱羰反应可以遵循几种途径。

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.

  一种缓蚀颜料，由稀土元素和价态稳定剂结合形成稀土/价态稳定剂复合物。稀土元素选自铈、铽、镨或它们的组合，至少有一种稀土元素处于四价氧化态。使用无机或有机材料来稳定四价稀土离子，以形成稀溶于水的化合物。选择特定的稳定剂是为了控制四价铈、铽或镨在遇水时的释放率，并调整粉末在所选粘合剂体系中用作颜料时的相容性。稳定剂还可以改变成型粉末的加工和处理特性。本文介绍了许多稀土-价稳定剂组合，其性能可与传统的六价铬体系媲美。

• A high yielding, one-pot synthesis of O,S-dialkyl dithiocarbonates from alcohols using Mitsunobu’s reagent
  作者：Devdutt Chaturvedi、Suprabhat Ray

  DOI：10.1016/j.tetlet.2006.10.149

  日期：2007.1

  A novel Mitsunobu-based protocol has been developed for the synthesis of O,S-dialkyl dithiocarbonates from a variety of primary, secondary and tertiary alcohols using carbon disulfide, in good to excellent yields. This protocol is mild and efficient compared to other reported methods. (c) 2006 Elsevier Ltd. All rights reserved.
