The fire toxicity of polyurethane foams [Review] [PDF]

, 2016
Polyurethane is widely used, with its two major applications, soft furnishings and insulation, having low thermal inertia, and hence enhanced flammability.

Chemical Methods for Peptide and Protein Backbone Cleavage

ChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Catch and release’ cascades: a resin-mediated three-component cascade approach to small molecules [PDF]

, 2006
The application of a ‘catch and release’ approach to palladium-catalysed multi-component cascade reactions leads to diverse libraries of pharmacologically interesting small molecules in high yield and with excellent ...

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

Isocyanate toughened pCBT: Reactive blending and tensile properties

eXPRESS Polymer Letters, 2013
Cyclic butylene terephthalate oligomers (CBT) were reacted in a ring-opening polymerization with three types of isocyanates: a bifunctional aromatic type, a bifunctional aliphatic type and a polymeric aromatic isocyanate.

(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

Chemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

Development of thermally stable phosphonitrile elastomers for advanced aerospace structures [PDF]

Both high and low molecular weight, curable poly(fluoroalkoxy phosphazene) terpolymers were prepared. These terpolymers resulted from reaction of (Cl2PNn) polymer with alkoxides derived from CF3CH2OH and C3F7CH2OH, and an alkoxide derived from CH3CH(OH ...

Automated synthesis of monodisperse oligomers, featuring sequence control and tailored functionalization [PDF]

, 2016
Long, multifunctional sequence-defined oligomers were obtairred on solid support from a protecting-group-free two-step iterative protocol, based on the inherent reactivity of a readily available molecule containing an isocyanate and a thiolactone ...
