Crown Ether Acetals: Synthesis and Characterisation of a Family of Novel Oxygen Macrocyclic Compounds

The synthesis of cyclic acetals containing a repetitive -CH2CH2O- grouping within the ring is described.Compounds with rings of up to thirty-four members and with one or two acetal groups have been prepared and characterised by their 1H and 13C n.m.r. spectra, the amount of acetaldehyde released on hydrolysis, and their molecular weights.The general formulae of the new compounds are CH3CH(OCH2CH2)nO with n = 2-6; CH3CH(OCH2CH2)nOCH(CH3)(OCH2CH2)nO, with n = 2-5; RCH(OCH2CH2)2O with R = Pr, Pri, Ph; and C6H4O(CH2CH2O)nCH(CH3)(OCH2CH2)nO, with n = 0, 1, 2.As precursors for compounds related to the last of these series, the new open-chain dichloroacetals CH3CH2, with n = 2, 3 were prepared.Rate constants for the acid catalysed hydrolysis of some of the new acetals are reported.
