Interaction of formaldehyde with a water-tolerant frustrated Lewis pair.

A facile complexation of formaldehyde with the water-tolerant frustrated Lewis pair (FLP) B(CF)/PtBu and its Al-analog under ambient conditions is reported. Unprecedented formaldehyde adducts 1, 2 and 4 have been identified and crystallographically characterized.

Transparent Films from CO2 -Based Polyunsaturated Poly(ether carbonate)s: A Novel Synthesis Strategy and Fast Curing.

Transparent films were prepared by cross-linking polyunsaturated poly(ether carbonate)s obtained by the multicomponent polymerization of CO2 , propylene oxide, maleic anhydride, and allyl glycidyl ether. Poly(ether carbonate)s with ABXBA multiblock structures were obtained by sequential addition of mixtures of propylene oxide/maleic anhydride and propylene oxide/allyl glycidyl ether during the polymerization. The simultaneous addition of both monomer mixtures provided poly(ether carbonate)s with AXA triblock structures.

Anion effect controlling the selectivity in the zinc-catalysed copolymerisation of CO2 and cyclohexene oxide.

The choice of the anion has a surprisingly strong effect on the incorporation of CO2 into the polymer obtained during the zinc-catalysed copolymerisation of CO2 and cyclohexene oxide. The product span ranges from polyethercarbonates, where short polyether sequences alternate with carbonate linkages, to polycarbonates with a strictly alternating sequence of the repeating units. Herein, we report on the influence of the coordination ability of the anion on the selectivity and kinetics of the copolymerisation reaction.

A new one-pot hydroformylation/Strecker synthesis as a versatile synthetic tool for polyfunctional compounds and functionalization of dendrimers.

A versatile and high yielding one-pot hydroformylation/Strecker synthesis is reported for the synthesis of various alpha-aminonitriles. This methodology allows functionalization of dendrimers (e.g.
