Novel pathways of interaction of maleic anhydride derivatives with phosphorus(III) compounds: synthesis and characterisation of N,N,N′,N′-tetraethyl-2,3-diphenylbut-2-enediamide and 3-dihydrofuranylidene-4-phosphorylidene-oxolane-2,5,5′-trione
Chemical Papers, 2015Co-Authors: Lenar I. Musin, Andrei V. Bogdanov, Dmitry B. Krivolapov, Alexey B. Dobrynin, Rashid Z. Musin, Viktor N. Khrustalev, Vladimir F. MironovAbstract:Maleic anhydride undergoes C -phosphorylation under the action of tris(diethylamino)phosphine to afford 3-dihydrofuranylidene-4-phosphorylidene-oxolane-2,5,5′-trione whereas 2,3-diphenylmaleic anhydride under the same conditions turns into N , N , N ′, N ′-tetraethyl-2,3-diphenylbut-2-enediamide. The latter reaction can serve as a novel approach for the synthesis of dicarboxylic acids diamides from corresponding cyclic Anhydrides. Their structures were established by NMR and X-ray diffraction.

semi aromatic polyesters by alternating ring opening copolymerisation of styrene oxide and Anhydrides
Polymer Chemistry, 2012Co-Authors: Elham Hosseini Nejad, Anita Paoniasari, C Cor E Koning, Rob DuchateauAbstract:Ring-opening copolymerisation of styrene oxide with alicyclic Anhydrides containing different ring strains (succinic anhydride, maleic anhydride, citraconic anhydride, cyclopropane-1,2-dicarboxylic acid anhydride, cyclopentane-1,2-dicarboxylic acid anhydride and phthalic anhydride) was performed applying metal salen and tetraphenyl porphyrin complexes where for (salen)MX, M = Cr, X = Cl (1), M = Al, X = Cl (2), M = Mn, X = Cl (3), M = Co, X = OAc (4) and salen = N,N-bis(3,5-di-tert-butylsalicylidene)-diimine and for porphyrin complex, M = Cr, X = Cl (5), M = Mn, X = Cl (6), M = Co, X = OAc (7). The chromium catalysts performed best and therefore 1 was chosen as the selected catalyst for further studies. Investigation of the effect of different cocatalysts on the copolymerisation of styrene oxide and phthalic anhydride revealed that phosphines and onium salt showed quite similar activities whereas N-heterocyclic based amines showed somewhat lower activity. 1H NMR and MALDI-ToF-MS spectra of the copolymers formed confirmed the alternating microstructures. Increasing the monomer to catalyst ratio resulted in the isomerisation of styrene oxide to phenyl ethanal. The aldehyde functions as a chain transfer agent influencing the molecular weight of the polymers. Copolymerisation of styrene oxide with Anhydrides bearing a double bond in their structure, such as maleic anhydride and citraconic anhydride, was shown to be highly dependent on temperature, time, type of cocatalyst and solvent used in the copolymerisation reaction.

ring opening co and terpolymerization of an alicyclic oxirane with carboxylic acid Anhydrides and co2 in the presence of chromium porphyrinato and salen catalysts
Macromolecules, 2011Co-Authors: Saskia Huijser, C Cor E Koning, Elham Hosseininejad, R Rafael J Sablong, Chris De Jong, Rob DuchateauAbstract:Copolymerization of cyclohexene oxide (CHO) with alicyclic Anhydrides applying chromium tetraphenylprophyrinato (TPPCrCl, 1) and salophen (SalophenCrCl, 2) catalysts resulted in polyesters or poly(ester-co-ether)s, depending on the nature of the catalyst, presence of a cocatalyst, solvent and type of anhydride. The combination of 1 as catalyst and 4-N,N-dimethylamino-pyridine (DMAP) as cocatalyst in the copolymerization of CHO with succinic anhydride (SA), cyclopropane-1,2-dicarboxylic acid anhydride (CPrA), cyclopentane-1,2-dicarboxylic acid anhydride (CPA) or phthalic anhydride (PA) invariably resulted in a completely alternating topology and therefore a pure polyester. Contrarily, 2 in combination with DMAP did not afford pure polyesters for the copolymerization of CHO with SA or CPrA but did render the alternating topology when CPA or PA was used as anhydride comonomer. Water proved to be an efficient bifunctional CTA affording α,ω-hydroxyl-terminated polyesters without loss of catalytic activity. Whe...
