  Using Rh(III)-Catalyzed C–H Activation as a Tool for the Selective Functionalization of Ketone-Containing Molecules

  摘要：

  Due to the strong potential of C H activation in many areas of organic chemistry, the use of a pre-existing carbonyl group for the installation of a directing group to enable selective and predictable alpha-alkenylation with activated olefins as coupling partners is described. This Heck-type reaction would then lead either to beta,gamma-unsaturated ketones or to variously substituted 1,4-butadienes depending on the conditions used for the cleavage of the directing group.

  A process is disclosed for the preparation of aralkyl mono-and diurethanes or ureas by carbamylmethylation, or acid-catalyzed addition at a temperature of 40°C to about 100°C of formaldehyde and esters of carbamic acid to aromatic hydrocarbons. Aralkyl carbamates and ureas formed by this process can be cracked directly to produce aralkyl diiso­cyanates, or hydrogenated and then cracked to produce ali­phatic diisocyanates, or reacted directly with polyols to produce polyurethanes by functioning as blocked isocyanates.

  本发明公开了一种通过氨基甲酰基甲基化或在 40°C 至约 100°C 的温度下将甲醛和氨基甲酸酯与芳香烃进行酸催化加成来制备烷基单氨基甲酸乙酯和二氨基甲酸乙酯或脲的工艺。 通过该工艺形成的烷基氨基甲酸乙酯和脲可直接裂解以生产烷基二异氰酸酯，或先氢化再裂解以生产脂肪族二异氰酸酯，或直接与多元醇反应，通过作为封端异氰酸酯来生产聚氨酯。
