Synthesis, crystal structures and reactivity towards dioxygen of copper(I) complexes with tripodal aliphatic amine ligands

Copper(I) complexes of the tripodal, tetradentate, aliphatic ligands Me3tren (Me3tren = tris-(2-methylaminoethyl)amine), Isoprop3tren (Isoprop3tren = tris-(2-isopropylaminoethyl)amine) and Me3isoprop3tren (Me3isoprop3tren = tris-(2-isopropylmethylaminoethyl)amine) of the Tren-family (Tren = tris(2-aminoethyl)amine) were prepared and structurally characterized. Furthermore, they were reacted in solution at low temperatures with dioxygen. All complexes formed a short-lived superoxido intermediate complex that could be observed using low temperature stopped-flow techniques prior to consecutive reactions. However, the superoxido complexes were too reactive to allow isolation and full characterization in contrast to previous work.

Reduction of copper(II) complexes of tripodal ligands by nitric oxide and trinitrosation of the ligands

The copper(II) centers in two copper(II) complexes of tripodal amine ligands, in acetonitrile solvent, upon exposure to nitric oxide have been found to produce a thermally unstable [CuII-NO] intermediate followed by the reduction of copper(II)

Synthesis of new proazaphosphatranes and their application in organic synthesis

We report herein the synthesis of the new proazaphosphatrane strong bases P(RNCH2CH2)3N (R=Me3CCH2, Me2CHCH2) and P(HNCH2CH2)2NCH2CH2 N-i-Pr (1g). The new azaphosphatranes [HP(RNCH2CH2)3N]Cl (R=Me3CCH2, Me2CHCH2) have P-Nax distances of 2.047 and 1.958 ?, respectively. We also report the synthesis of the tetramine precursor proazaphosphatrane 1g [namely, (H2NCH2CH2) 2NCH2CH2NH-i-Pr] in 41% yield and the use of a complexation-extraction technique to separate it from a mixture containing the di- and tri-isopropyl substituted analogs. Using a 31P NMR technique, we report the pKa value for 1gH+ (34.49). The catalytic properties of three bases P(RNCH2CH2)3N (R=i-Pr, Piv, i-Bu) are compared in the synthesis of several β-hydroxy nitriles, β-nitroalkanols, α,β-unsaturated esters and for the Michael addition of allyl alcohol to α,β-unsaturated ketones.

Synthesis of a novel exceedingly strong nonionic superbase

The synthesis of a novel superbase P(HNCH2CH2)(i-PrNCH2CH2) 2N, 2a, is discussed. The conditions for the preparation and purification of H2NCH2CH2N(CH2CH 2N-i-Pr)2. 4a, starting from commercially available (H2NCH2CH2)3N (tren) were optimized. The existence of the novel zwitterion HP(N-CH2CH2)(i-PrNCH2CH 2)2N+, 2b, was substantiated by NMR spectroscopy. The Superbase 2a crystallizes from its melt when cooled slowly to -4 °C, and then remains as a solid at room temperature for several days. Hence it can be handled as a liquid or as a solid.
