Investigations on vinylene carbonate, 2. Copolymerization with N-vinyl-2-pyrrolidone and ethyl vinyl ether [PDF]
, 1990 Functional monomers and polymers have received considerable attention in recent years, especially in the biomedical field. In this respect, poly(viny1ene carbonate) is very interesting, because the reactive carbonate groups offer the possibility of ...

Vinyl sulfones: selective and tunable covalent warheads against challenging enzyme targets [PDF]
Exploration of Drug ScienceOver the past several decades there has been a growing recognition of the role that covalent drug candidates have played in the drug development process. With this recognition, compounds that are capable of selectively and irreversibly inactivating their

Vinyl Polymerizationby Organocalcium Compound.
The Journal of the Society of Chemical Industry, Japan, 1959 カルシウムテトラエチル亜鉛CaZn(C2H5)4が,スチレン,メタクリル酸メチルおよびアクリロニトリルなどのビニル化合物に対して有効な重合触媒となることがわかった。カルシウムテトラエチル亜鉛は,Gilmanの方法によって,ジェチル亜鉛とカルシウム金属とから合成した。酢酸ビニル,塩化ビニル,アクリル酸メチルなどはこの触媒では重合しなかった。酸素,キノン類などはこの重合を抑制した。メタクリル酸メチルとスチレンとの共重合では,典型的な「陰イオン的」単量体反応性比が見出された。動力学的研究の結果,見かけの活性化エネルギーの値はかなり小であり,また1分子停止機構が妥当と考えられる。これらの事実の重合反応が陰イオン機構によっていることを支持する。この触媒によって得られたポリスチレンについて,赤外吸収スペクトル ...

Oxycyanation of Vinyl Compounds
The Journal of the Society of Chemical Industry, Japan, 1971 イソプチレン, スチレン, 塩化ビニル, アクリロニトリルならびにベンゼンのナキシシアン化反応を行なった。イソブチレンからはβ,β-ジメチルアクリロニトリルが生成した。イソブチレンのオキシシアン化反応の動力学的挙動はエチレンに似ている。スチレンからは cis-β-ならびに trans-β-フェニルアクリロニトリルが生成した。塩化ビニルからはα-, cis-β- ならびに trans-β-クロロアクリロニトリルが得られた。β-クロロアクリロニトリルより逐次的にフマロニトリルが生成した。アクリロニトリルのオキシシアン化によりフマロニトリルが得られたが, その量は塩化ビニルのオキシシアン化により得られたフマロニトリルよりぎわめて少なかった。ベンゼンよりベンゾニトリルが得られた ...
