Intramolecular hydrogen-bonded tertiary phosphines as 1,3,5-triaza-7-phosphaadamantane (PTA) analogues
journal contribution
posted on 2014-09-29, 14:19 authored by Allen T. Ekubo, Mark ElsegoodMark Elsegood, Andrew Lake, Martin SmithMartin SmithNew cationic trialkylphosphines [P(CH2NH2R){CH2N(R)CH2N(R)CH2}]+ (R ) C6H5CH2, a; 4-FC6H4CH2, b), as their
Cl- (1a, 1b), SbF6
- (2a, 2b), and PF6
- (3a, 3b) salts, are described. The phosphine framework is conformationally
locked, in the solid state, through pairs of intramolecular N-H · · · N hydrogen bonds which are maintained in the
RuII and RhIII complexes 4 and 5. Phosphines 1a-3b can be considered as charged variants of the well-known
PTA ligand.
