Potentiometric Data

Sodium ion complex formation has been investigated potentiometrically in four homologous bis(crown) series I-IV differing by the nature of substituent placed at the linking trimethylene chain (X = OH, OCH3, OCH2C6H5 and H respectively). A marked enhancement of the complex stability has been observed in the bis(crown) series I and attributed to participation of the lateral hydroxyl group in the sandwich complex formation. Evidence in support of the sandwich structure has been provided (i) by analysis of the potentiometric data indicating a 1:1 complex stoichiometry and (ii) by a comparison of the complex stability data from the bis(crown) series I with the corresponding values from related monocyclic ligand series V, VI and VII revealing a pronounced cooperation of both macrorings in the sodium ion-bis(crown) I complex formation.

The reduction of 1,4-diphenyl-1,4-bis(diphenylphosphanyl)buta-1,3-diene (1) (1,4-diphenyl- NUPHOS) with potassium in THF yields bis(THF)potassium 2,5-diphenylphospholide (2) which crystallizes with a chain structure. The metathesis reaction of 2 with the iodides of calcium, strontium, and barium leads to the formation of [bis(THF)calcium bis(2,5-diphenylphospholide)] (3), [bis(THF)strontium bis(2,5-diphenylphospholide)] (4), and [bis(THF)barium bis(2,5-diphenylphospholide)] (5). The reaction of M{P(H)SiiPr3}2 with diphenylbutadiyne in THF also leads to the formation of the 2,5-diphenylphospholides of calcium (3), strontium (4), and barium (5). The molecular structures of 2 to 4 are discussed. The environment of the metal atoms is very similar in all these compounds: The metal atoms show an η5 coordination to the phospholide rings forming a bent sandwich complex. The open coordination site is occupied by two THF molecules
