Solvent-free and solvent-less slipping-on of the dibenzo-24-crown-8 (DB24C8) over the -hydroxysuccinimide end of an ammonium-containing thread has been studied and compared to the same reaction operated in solution. Slippage proved to be possible in solvent-free conditions, but the fastest slippage was obtained under heating when preliminary Liquid-Assisted Grinding (LAG) conditions were applied to the reactants followed by aging under an atmosphere of acetonitrile.
研究了二苯并 - 24 - 冠 - 8（DB24C8）在含铵链的羟基琥珀酰亚胺端上的无溶剂和少溶剂滑环反应，并与在溶液中进行的相同反应进行了比较。结果表明，在无溶剂条件下滑环反应是可行的，但在对反应物施加初步的液相助磨（LAG）条件，然后在乙腈气氛中老化后加热时，滑环反应速度最快。
