Mitsunobu Reactions Catalytic in Phosphine and a Fully Catalytic System
The Mitsunobu reaction is renowned for its mild reaction conditions and broad substrate tolerance, but has limited utility in process chemistry and industrial applications due to poor atom economy and the generation of stoichiometric phosphine oxide and hydrazine by-products that complicate purification. A catalytic Mitsunobu reaction using innocuous reagents to recycle these by-products would ...
متن کاملBis(allenylidene) Complexes of Palladium and Platinum
trans-Bis(alkynyl)palladium complexes, trans-[(PEt3)2Pd(-CtCC{dO}NR2)2] (NR2 = NMe2 (2a), N(CH2)4 (2b)), were synthesized by two different methods: (a) by copper-catalyzed reaction of HCtCC(dO)NR2with [PdCl2(PEt3)2] under basic conditions and (b) by treatingHCtCC(dO)NR2 with AgNO3 followed by transmetalation of the alkynyl ligand from silver to [PdCl2(PEt3)2]. The reaction of AgCtCC(dO)NMe2 (3a...
متن کاملTetrabenzporphyrin Complexes of Iron, Palladium and Platinum
The syntheses and absorption spectra of Fe(II)TBP(pyridine)2, Pd(II)TBP, and Pt(II)TBP (TBP = Tetrabenzporphyrin) are reported. The emission spectra of PdTBP and PtTBP were measured. Both complexes exhibit only phosphorescence from the lowest triplet of TBP. The Fe complex was oxidized to the cation [FeTBP(pyn*dine)J+ which was characterized by its absorption and ESR spectrum. The emission spec...
متن کاملortho-Metallated triphenylphosphine chalcogenide complexes of platinum and palladium: synthesis and catalytic activity.
Treatment of [PtI2(COD)] (COD = 1,5-cyclooctadiene) with 2-LiC6H4P(S)Ph2 gives the complex cis-[Pt{κ(2)-2-C6H4P(S)Ph2}2] () containing a pair of ortho-metallated triphenylphosphine sulfide rings. The selenium counterpart, [Pt{κ(2)-2-C6H4P(Se)Ph2}2] (), which exists as cis- and trans-isomers in solution, and the palladium analogues, cis-[Pd{κ(2)-2-C6H4P(X)Ph2}2] [X = S (), Se ()], are obtained b...
متن کاملSynthesis, Structure and Catalytic Studies of Palladium and Platinum Bissulfoxide Complexes
The bis-sulfoxide ligand p-tolyl-binaso and its derivatives can be used to synthesize neutral and cationic palladium and platinum complexes. Various Pt bis-sulfoxide complexes could be made by using the precursor Pt(M,SS,SS)-p-tolyl-binasoCl2 (5a) and abstracting the chlorides with silver salts. The Pd analogue of this compound (4) could not be used in the same way. In this case, the sulfoxides...
