INTRAMOLECULAR [4+2] DIELS-ALDER CYCLOADDITIONS OF 2-SUBSTITUTED PHOSPHABENZENE AND ARSABENZENE IN TRIOSMIUM CLUSTERS
(Amer. Chem. Soc., 1994-09)
2-(Trimethylsilyl)-1-phosphabenzene and -1-arsabenzene, Me(3)SiC(5)H(4)E (E = P, AS), react with [Os3H2(CO)(10)] to give the clusters [Os3H2(Me(3)SiC(5)H(4)E)(CO)(9)], which contain sigma-bonded, four-electron-donating mu ...
Nonacarbonyl[μ 3-(1,2-diphenylethyl)-phenylphosphinito]triosmium(2 Os-Os)
(Blackwell Munksgaard, 1997)
The reaction of 1,2,3-triphenylphosphirene with [H2Os3-(CO)10] leads to the title compound, [Os3(CO)9{(C6H5)3-C 2PO}], which displays an open Os3(CO)9 cluster [Os-Os 2.703 (1) and 2.867 (2) Å, and Os-Os-Os 124.24 (4)°]. ...
Nonacarbonyl[mu(3)-(1,2-diphenylethyl)-phenylphosphinito]triosmium(2 Os-Os)
(MUNKSGAARD INT PUBL LTD, 1997-03-15)
The reaction of 1,2,3-triphenylphosphirene with [H2Os3-(CO)(10)] leads to the title compound, [Os-3(CO)(9){(C6H5)(3)-C2PO}], which displays an open Os-3(CO)(9) cluster [Os-Os 2.703(1) and 2.867(2) Angstrom, and Os-Os-Os ...
