Abstract

The dimeric macrocycles [{P (μ-NtBu)} 2· LL] 2 [LL= OCH2C (Me) 2CH2O (1), 2, 6-(NH) 2C5H3N (2), 1, 2-(NH) 2C6H4 (3)] have been obtained by the reactions of the appropriate diols and diamines (LLH2) with the dimeric phosph (III) azane [ClP (μ-NtBu)] 2. Under different conditions the reaction of 1, 2-(NH2) 2C6H4 with [ClP (μ-NtBu)] 2 gives the monomer [{P (μ-NtBu)} 2·{1, 2-(NH) 2C6H4}](4)(instead of the dimer 3). Contrary to the ...
