New molecular receptors with dibenz[c,h]acridine skeleton bearing functiona
l groups complementary to malonic acids have been developed. Dibutylmalonic
acid is bound in chloroform with Kass values between 10(2) and 10(5) M-1 v
ia hydrogen-bonding interactions. The catalytic ability of several of these
receptors in the decarboxylative reaction of this diacid has been investig
ated. (C) 1999 Elsevier Science Ltd. All rights reserved.
