The Creation of a New System of Labor Relations in Russia Theses

In and of itself, the title of this paper requires clarification: strictly speaking, a system of labor relations does not as yet exist in Russia. The country is at the stage of making the transition from the old, administrative system to the new, market system. This system is in large measure created not from internal conditions but through borrowings from foreign experience. The borrowings are eclectic, from different systems, and lack any understanding of the wholeness and historical logic in every country.

First Evidence of 1,3-Bis-indolylallenes: Generation by a Sequential Double Nucleophilic Process from Ynones

<div><p></p><p>The first examples of 1,3-bis-indol-3-ylallenes (1,3-BIAs) are described. They have been generated by addition of a 3-lithioindole reactant to tetramethylsilane-protected mono- and di-alkynyl ketones. The one-pot preparation of 1,3-BIAs is enabled by both the double electrophilic character of the ynone substrates and the double nucleophilic character of the lithio-enamine function of the indolyl moiety, leading to a transient azafulvenium intermediate.</p> </div
