Salen supported Al–O–CP and Ga–PCO complexes

Salen-supported dinuclear and trinuclear boron compounds

Six boron compounds have been synthesized through the combination of phenylboronic acid and various Salen (N ,N ?ethylenebis(2-hydroxy)benzylidenimine) ligands. They contain sevenand eight-membered heterocycles with a bridging oxygen and have the formula: L[(PhB)2(m-O)] (L /Acmen (1), Salen( Bu) (2), Sal(2-OH)pen (3), Salpen( Bu) (4), Acpen (5)) and L[B2(mO)(O2BPh)] (L /Acen (6), Salmen (7)). C...

Binuclear (salen)osmium phosphinidine and phosphiniminato complexes.

The preparation of a number of binuclear (salen)osmium phosphinidine and phosphiniminato complexes using various strategies are described. Treatment of [Os(VI)(N)(L(1))(sol)](X) (sol = H(2)O or MeOH) with PPh(3) affords an osmium(IV) phosphinidine complex [Os(IV){N(H)PPh(3)}(L(1))(OMe)](X) (X = PF(6)1a, ClO(4)1b). If the reaction is carried out in CH(2)Cl(2) in the presence of excess pyrazine t...

Highly electrophilic (salen)ruthenium(VI) nitrido complexes.

A series of cationic ruthenium(VI) nitrido species containing the cyclohexyl-bridged salen ligand (L) and its derivatives, [RuVI(N)(L)]+, have been prepared by treatment of [NBun4][RuVI(N)Cl4] with H2L in methanol. The structure of [RuVI(N)(L)](ClO4) (1a) has been determined by X-ray crystallography, d(RuN) = 1.592 A. In solvents such as DMF or DMSO, [RuVI(N)(L)]+ undergoes a facile N...N coupl...

Detection of potentially toxic metals by SERS using salen complexes.

Surfaced enhanced Raman scattering (SERS) can discriminate between metal complexes due to the characteristic "spectral fingerprints" obtained. As a result, SERS has the potential to develop relatively simple and sensitive methods of detecting and quantifying a range of metal ions in solution. This could be beneficial for the environmental monitoring of potentially toxic metals (PTMs). Here, sal...
