, p. 912 - 916 (1993)
A number of monopodands having o-diphenylphosphinyl terminal groups were synthesized by alkylating sodium derivatives of oligoethylene glycols with o-(bromomethyl)phenyldiphenylphosphine.The stability constants of the complexes of these ligands with alkal

, p. 230 - 235 (2018/12/05)
A series of new optically pure phosphine oxides containing chiral aziridine subunit were synthesized in good yields and applied as organocatalysts in asymmetric Michael reaction of various aliphatic aldehydes with β-nitrostyrene. The corresponding organoc
A tandem olefin migration and Prins cyclization using Cu(OTf) 2-bisphosphine complexes: An improved synthesis of functionalized tetrahydropyrans

supporting information; experimental part, p. 3699 - 3702 (2012/09/21)
In situ-generated (bis-DPPMB)-Cu(OTf)2 complex has been examined to catalyze a tandem olefin migration and Prins cyclization of an alkenol with various aldehydes. The reaction proceeded with electron-rich aromatic aldehydes at room temperature
