A Tosylation of primary alcohol with tosyl chloride was performed effectively with an N-hexadecylimidazole catalyst in water containing K2CO3. aggregation of the catalyst carrying a hydrophobic methylene chain worked as a substitute for organic solvent.
N-十六烷基咪唑催化剂可在含K 2 CO 3的水中有效地进行伯醇与甲苯磺酰氯的甲苯磺酸酯化反应。带有疏水性亚甲基链的催化剂的聚集体用作有机溶剂的替代物。

Novel diheteroatom-substituted fatty acid analog substrates of myristoylating enzymes are provided which contain oxyen and/or sulfur in place of two methylene groups in carbon positions from 3 to 13 in the fatty acid chain of a C.sub.13 -C.sub.14 fatty acid analog or alkyl ester thereof in which said oxygen or sulfur atoms are separated by at least one methylene group.
