The crystal structure of 1, 3-dimethyl-1, 3-propane dionatobis(triphenylphosphite)rhodium(I)

Novel rhodium complexes with N-pyrrolylphosphines: attractive precursors of hydroformylation catalysts

“…The Rh᎐P bond distance [2.1657(7) Å] is similar to that in phosphite complexes e.g. [Rh(acac)- 21 Complex 2a is almost square planar and the average deviation from the best plane is 0.05 Å (Fig. 2).…”

“…{P(OPh) 3 } 2 ] 2.147(2), 2.156(2) Å,21 but shorter than in phosphine complexes, e.g. [Rh(acac)(CO)(PPh 3 )] 2.244(2) Å,14 [Rh(quin)(CO)(PPh 3 )] 2.261(2) Å (Hquin = 8-hydroxyquinoline),22 and [Rh(trop)(CO)(PPh 3 )] 2.232(2) Å [Htrop = tropolone (2-hydroxycyclohepta-2,4,6-trienone)] 23.…”

A density functional theory study of the oxidative addition of methyl iodide to square planar [Rh(acac)(P(OPh)3)2] complex and simplified model systems

“…This was addressed by comparing the known single crystal X-ray diffraction structure (Fig. 2 [28] (1), tfba [29] (2), tfaa [30] (3)) and [Rh III (b-diketonato)(P(OPh) 3 ) 2 (I) 2 ] (bdiketonato ¼ tfaa [31] (4)) (Htfba ¼ trifluorobenzoylacetone and Htfaa ¼ trifluoroacetylacetone) with the theoretically calculated structure of the same complex.…”

Structure, Electrochemistry and Hydroformylation Catalytic Activity of the Bis(pyrazolylborato)rhodium(I) Complexes [RhBp(CO)P] [P = P(NC4H4)3, PPh3, PCy3, P(C6H4OMe‐4)3]

“…The Rh−PPh 3 bond in complex 2 [2.2614(5) Å] is longer than those in the related complexes [RhBp(PPh 3 ) 2 ] [2.2261(9) and 2.2503(10) Å]26 and [Rh(acac)(CO)PPh 3 ] [2.244(2) Å],27 but shorter than that in [RhTp′(CO)PPh 3 ] [2.272(2) Å] 28. The Rh−PCy 3 bond in 3 [2.2613(10) Å] is relatively short when compared with the Rh−PCy 3 bonds in [RhBp(CO)PCy 3 ] [2.2808(12) Å], [RhTp′(CO)PCy 3 ] [2.292(1) Å],28 [HRh(CO)(PCy 3 ) 2 ] [2.290(1), 2.297(1) Å]29 and in other acetylacetonatorhodium complexes: [Rh(acac){( E )‐CH=CHCy}(PCy 3 ) 2 ]BF 4 [2.336(3), 2.357(3) Å]30 and [Rh(acac){CH=C=CPh 2 }(PCy 3 ) 2 ]BF 4 [2.285(2) Å] 31. Such a short Rh−PCy 3 bond has, until now, only been reported for [Rh(acac)(PCy 3 ) 2 ] [2.252(1), 2.260(1) Å] 30…”
