摘要:N,N,N',N'-四甲基甲酰胺盐酸盐(2A)在不同溶剂中与金属钠反应反应生成n,N,N',N',N'',N''-六甲基胍盐酸盐(4A).与钾反应得到n,N,N',N',N'',N'',N''',N'''-八甲基氧胺盐酸二盐(3A).在不同溶剂中,2A与镁反应通常反应生成盐酸盐4A,3A和n,N,N',N'-四甲基甲酰胺盐酸盐(10A)的混合物.这些混合物的组成取决于溶剂和反应温度.当使用锌/铜偶联代替镁时,也会得到类似的结果.很可能从2A和镁或锌中分别形成有机金属中间体11,12,这些中间体可以被芳香醛和苯基异氰酸酯捕获.盐2A可以通过低价钛试剂还原偶联形成氧胺盐3A.

摘要:A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from −50° C. (223 K) to 200° C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.
