Bis(but-2-enoato-κ<i>O</i>)triphenylbismuth(V)

“…Normally, these compounds are prepared in a two-step process, first by reacting BiPh 3 with chlorine or bromine to produce Ph 3 BiX 2 followed by reaction with an alkali-metal salt of an appropriate anionic ligand . Several examples of BiPh 3 (O 2 CR) 2 have been reported previously (R = Me, , Et, Ph, , Bu, CHCH 2 , Me(CH 2 ) 8 , Me(CH 2 ) 10 , oxalate, p -OHC 6 H 4 CH 2 CH 2 , Cl 3 C, ClCH 2 , BrCH 2 , F 3 C, 3-MeC 6 H 4 , 4-MeC 6 H 4 , 2-AcOC 6 H 4 , F 5 C 6 , 3,4,5-F C 6 H 2 , C 3 H 5 ). Bi(V) compounds have been studied extensively as aryl transfer reagents in organic synthesis. − We have presumed that the reaction proceeds through the intermediacy of Ph 3 BiO, but attempts to isolate that compound or to detect it spectroscopically in solution were not successful.…”

Triphenylbismuth(V) bis(carboxylates), Ph 3 Bi(O 2 CR) 2 (R = 5-Br-2-OH-C 6 H 3-(1), 2-OH-C 6 H 4-(2), 2,6-(OH) 2-C 6 H 3-(3); 3-Me-2-NH 2-C 6 H 3-(4); Ph-(5) and Me-(6)) were obtained from the reaction of triphenylbismuth with hydrogen peroxide and excess carboxylic acid in wet 2-propanol. The synthesis avoids the use of halogens as oxidants and the products crystallize directly from the solution as pure compounds. They crystallize from solution without further need of purification. The structures of 1-5 were confirmed by single crystal X-ray diffraction. Compounds 2 and 5 exhibit a different polymorph than that previously reported in the literature. While all of the Bi(V) compounds adopt a trans-axial trigonal-bipyramidal configuration with the carboxylates in the axial positions, there is considerable variation in the coordination of the carboxylate that ranges from simple monohapto to the mixture of monoand bidentate chelating bonding modes.

Decomposition of triphenylbismuth dicrotonate in diffused light in bensene in the presence of spin trap of C-phenyl-N-tert-butylnitrone leads to formation of phenyl radicals which are registered as the adduct PhCH(Ph)N(O•)Bu-t.Triphenylbismuth dicrotonate Ph3Bi(O2CCH=CHCH3)2 in benzene solition in the presence of C-phenyl-N-tert-butylnitrone PhCH=N(O)Bu-t decomposes in light. An adduct of phenyl radical and spin trap PhCH(Ph)N(O•)Bu-t was registered by ESR method.
