Selective recognition of neutral molecules: 1H n.m.r. Study of the complexation of CH2Cl2 and CH2Br2 by cryptophane-D in solution and crystal structure of its CH2Cl2cavitate
Abstract
The complexation of CH2Cl2 and CH2Br2 by cryptophane-D (2), a new bis-cyclotribenzyl cavitand, has been studied by 1H n.m.r. spectroscopy and the structure of the internal 1 : 1 (2)·CH2Cl2 complex (cavitate) has been determined by single crystal X-ray crystallography.
