Unusual reactivity of aliphatic and aromatic amines with bromoalkyl derivatives of thiacalix[4]arene in 1,3-alternate stereoisomeric form

© ISUCT Publishing. For the first time a series of new cationic amphiphilic p-tert-butylthiacalix[4]arene derivatives adopting 1,3-alternate stereoisomeric form was synthesized by quaternization of several tertiary amines and N-heterocycles. The structure of all products was well-defined using modern physical technics. The influence of calixarene and amine sterical hindrances on reactivity is discussed

NEW HIGHLY EFFICIENT CATALYTIC SYSTEMS BASED ON MULTIDENTATE POLYMER PARTICLES, FORMED BY SELF-ASSEMBLY OF CALIX[4]ARENES

Metal complex catalysis, allowing modification of molecules with atomic precision, leads to a significant saving of resources and by-products decrease and, therefore, completely corresponds to several principles of “green chemistry”. However, it should be worth considering that homogeneous metal complex catalysts can be used only once. Taking into account the high cost of noble metals, the use of homogeneous catalysts becomes a very expensive procedure, especially in industrial scale.The author s gratefully acknowledge of the RSF (19-13-00095) and RFBR (19-03-00519) for the financial support
