  • Nickel‐Catalyzed Synthesis of <i>N</i> ‐(Hetero)aryl Carbamates from Cyanate Salts and Phenols Activated with Cyanuric Chloride

    one‐pot synthesis of N‐(hetero)aryl carbamates through the reaction between alcohols and in‐situ produced (hetero)aryl isocyanates in the presence of a nickel catalyst. The phenolic C−O bond was activated via the reaction of phenol with cyanuric chloride (2,4,6‐trichloro‐1,3,5‐triazine (TCT)) as an inexpensive and readily available reagent. This strategy provides practical access to N‐(hetero)aryl carbamates

  • SOME OBSERVATIONS ON CYANIC ACID AND CYANATES
    作者:M. W. Lister
    DOI:10.1139/v55-050
    日期:1955.2.1

    Various reactions of cyanic acid and the cyanate ion have been examined. Cyanic acid, in the presence of added hydrochloric or nitric acid, decomposes quantitatively according to the equation: HNCO + H3O+ → CO2 + NH4+. The rate constant for this reaction was measured over a range of temperature and ionic strength, and was found to be 0.86 mole liter−1 min.−1 at unit ionic strength and 1.5 °C. The activation energy is [Formula: see text] The effect of ionic strength on the reaction with hydrochloric acid closely parallels that on the activity coefficients of the acid itself. Without added acid cyanic acid decomposes by a first order reaction: HNCO + 2H2O → NH4HCO3, followed by a rapid second stage: NH4HCO3 + HNCO → NH4NCO + H2CO3. This reaction has a rate constant of 0.011 min.−1 at 0 °C. and an activation energy of 16 kcal. There is also a few per cent of some side reaction. Cyanate ions in alkaline solution decompose thus: OCN + 2H2O → NH4+ + CO3−−. This reaction was examined over a range of temperature and ionic strength: it is first order with k = 3.0 × 10−3 min.−1at 100 °C. (0.3 ionic strength) and [Formula: see text] activation energy. The rate is somewhat dependent on hydroxide concentration, when this is fairly low. The reaction is catalyzed by carbonate, but not by a number of other anions that were examined. The rate of the catalyzed reaction is proportional to the carbonate concentration, but independent of cyanate, at least over a considerable range. The ionization constant of cyanic acid has been measured by a method that avoids errors from hydrolysis; the value obtained was 2.0 × 10−4. The oxidation of cyanate by hypochlorite and by chlorine was examined more briefly.

    已经研究了氰酸氰酸盐的各种反应。在加入盐酸硝酸的情况下,氰酸会定量分解,反应式为:HNCO + H3O+ → CO2 + NH4+。该反应的速率常数在一定温度和离子强度范围内进行了测量,发现在离子强度为1.5°C时,该速率常数为0.86摩尔/升·分。激活能为[公式:见正文]。离子强度对于与盐酸反应的反应与酸本身的活度系数有密切的关系。如果没有加入酸,氰酸会通过一级反应分解:HNCO + 2H2O → NH4HCO3,然后是快速的第二阶段:NH4HCO3 + HNCO → NH4NCO + H2CO3。该反应在0°C时的速率常数为0.011分-1,激活能为16千卡。还有一些副反应约占几个百分点。碱性溶液中的氰酸盐分解如下:OCN- + 2H2O → NH4+ + CO32-。该反应在一定温度和离子强度范围内进行了研究:k = 3.0×10-3 min-1,100°C(0.3离子强度)为一阶反应,激活能为[公式:见正文]。当氢氧离子浓度相当低时,反应有些依赖于氢氧离子浓度。碳酸盐催化该反应,但其他一些被检测的阴离子并没有催化作用。催化反应的速率与碳酸盐浓度成正比,但至少在相当范围内与氰酸盐无关。通过避免解误差的方法,测定了氰酸的电离常数,得到的值为2.0×10-4。更简要地研究了次氯酸盐和气对氰酸盐的氧化作用。

    This paper reports the effectiveness of carrying out the cycloaddition reaction of styrene oxide (SO) and CO2 without the use of any catalysts. A naturally abundant and cheap material, urea, was utilized in promoting the reaction by controlling the reaction conditions. The influence of reaction temperature, carbon dioxide (CO2) pressure, amount of urea, and the reaction time on the selectivity of styrene carbonate (SC) was investigated.
