The structure and some reactions of allylcarbonyliron complexes, C3H5Fe(CO)3X, have been studied. Their decay was shown to proceed through, or without, addition of evolving CO, to the allyl radical. Dimethyl sulfoxide caused no π-σ- rearrangement but it completely replaced the allyl ligand.
研究了烯丙基羰基铁配合物C 3 H 5 Fe(CO)3 X的结构和一些反应。结果表明,它们的衰变是通过或不向烯丙基中添加不断发展的一氧化碳而进行的。二甲基亚砜没有引起π-σ-重排,但完全取代了烯丙基配体。

The invention provides a process for producing a β-dihydrofuran derivative represented by formula (1) or a β-tetrahydrofuran derivative represented by formula (4), characterized in that the process includes causing a dialkyl dicarbonate, a diaralkyl dicarbonate, or a halide to act on a diol compound represented by formula (2) or (3). The invention also provides a process for producing 4′-ethynyl-2′,3′-didehydro-3′-deoxythymidine or an analog thereof, the process including glycosylation and deprotection.
There is provided a novel process for producing an indole derivative which comprises cyclizing 2-nitrobenzylcarbony compound in the presence of a catalyst comprising a Group VIII metal of the Periodic Table, characterized by conducting the cyclization in a gas atmosphere containing carbon monoxide. The process enables an indole compound to be selectively produced in a high yield from 2-nitrobenzylcarbonyl compound, and hardly yields an indoline compound as a reduction by-product that has been a problem in the catalytic hydrogenation method employing a noble metal catalyst. The indole derivative produced by the present process is useful for various fine chemical intermediates including compounds and physiologically active substances such as pharmaceuticals and agrochemicals.

A process for the preparation of a sterically hindered amine ether which comprises reacting a corresponding sterically hindered aminoxide with a C5-C18alk-1-ene in the presence of an organic hydroperoxide and optionally hydrogenating the resulting product as well as the product mixtures obtained therewith and their use as stabilizers and flame retardants.
An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a polyisocyanate crosslinking agent; wherein the improvement is the use of a polyisocyanate crosslinking agent having at least one crosslinkable morpholine dione group per molecule. Electrodeposited finishes are formed that have reduced volatile emissions and film weight loss when heated to cure.
