TL;DR: In this article, the copolymerization of methyl vinyl ketone with propylene, isobutylene, styrene, vinyl chloride, and dienes like 1-vinylcyclohexene-(2) and butadiene was presented.
Abstract: Results are presented on copolymerization of methyl vinyl ketone with ethylene, propylene, isobutylene, styrene, vinyl chloride, and dienes like 1-vinylcyclohexene-(2) and butadiene. The ketone was complexed with ethyl- and methylaluminium compounds, aluminium chloride, and aluminium bromide. With ethyl- or methylaluminium dichloride as complexant, equimolar copolymers of methyl vinyl ketone and propylene, isobutylene, vinyl chloride, and butadiene were obtained in toluene solutions at −78°C. The other methyl and ethylaluminium compounds used, aluminium chloride, and aluminium bromide proved to be inactive in the copolymerization of the ketone and the monomers mentioned above.
Die Copolymerisation von Komplexen aus Methylvinylketon und Alkylaluminiumverbindungen bzw. AlCl3, oder AlBr3 mit Athylen, Propylen, Isobutylen, Styrol, Vinylchlorid, 1-Vinylcyclohexen-(2) und Butadien wurde untersucht. Mit Methyl- oder Athylaluminiumdichlorid als Komplexkomponente wurden in Toluol bei −78°C aquimolare Copolymere aus Methylvinylketon und Propylen, Isobutylen, Vinylchlorid oder Butadien erhalten. Komplexe aus Methylvinylketon und anderen Methyl- oder Athylaluminiumverbindungen oder mit AlCl3 bzw. AlBr3 waren gegenuber allen genannten Monomeren inaktiv.

TL;DR: Two domino reactions between salicyl N-thiophosphoryl imines and methyl vinyl ketone catalyzed by bifunctional phosphine catalysts and DBU provide two simple and efficient methods to construct chromans and chromens under mild conditions, respectively.
Abstract: We report two domino reactions between salicyl N-thiophosphoryl imines and methyl vinyl ketone catalyzed by bifunctional phosphine catalysts and DBU. These reactions provide two simple and efficient methods to construct chromans and chromens under mild conditions, respectively.

TL;DR: Tandem Michael additions of indole derivatives to 3-nitrocoumarins 2, followed by MVK, in one pot, has been developed for the synthesis of multi-functionalized 3,4-dihydrocou marins bearing a quaternary stereocenter with high diastereoselectivities.
Abstract: Tandem Michael additions of indole derivatives to 3-nitrocoumarins 2, followed by MVK, in one pot, has been developed for the synthesis of multi-functionalized 3,4-dihydrocoumarins bearing a quaternary stereocenter. The reaction proceeds with high diastereoselectivities in good to excellent yields.
