X. Delaigue et al., MULTICAVITANDS-II - SYNTHESIS OF A NONCENTROSYMMETRIC HOLLOW MOLECULAR UNIT (KOILAND) BASED ON FUSION OF 2 P-TERT-BUTYLCALIX[4]ARENES BY BOTH SILICON AND TITANIUM ATOMS, Tetrahedron letters, 34(47), 1993, pp. 7561-7564
The synthesis and NMR structural investigation of a non-centrosymetric
koiland (hollow molecular unit) composed of two p-tert-butylcalix[4]a
renes fused by both silicon and titanium atoms, and of its precursor o
btained by fusing two p-tert-butylcalix[4]arenes with a silicon atom w
ere achieved.
