This new volume substantially updates the original pyridazines volume which was published in 1973. Announcing the latest volume in the successful and prominent Chemistry of Heterocyclic Compounds Series.

1,2,3-Thiadiazoles are a group of heterocycles whose derivatives are important in industry, medicine, and agriculture. This volume provides a complete treatment of this group of heterocycles with an emphasis on syntheses, structural data, properties, reactions, and applications.

The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects - properties, synthesis, reactions, physiological and industrial significance - of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all...

A volume in the Chemistry of Heterocyclic Compounds series, this book provides a summary of the chemistry of each of the six naphthyridine systems along with tables of known simple derivatives with original references.
Each of the six naphthyridine systems are described in valuable detail and coverage includes: Primary synthetic methods from non-naphthyridine substrates; Chemistry and properties of the parent heterocycle and its simple alkyl derivatives; Formation and reactions of halogeno derivatives; formation and reactions of hydroxy, oxo, alkoxy, and related derivatives.

The old lawyer caressed his smoothly shaven chin and gazed out at Joyce Lavillotte from under his shaggy eyebrows, as from the port-holes of a castle, impressing her as being quite as inscrutable of aspect and almost as belligerent. She, flushed and bright-eyed, leaned forward with an appealing air, opposing the resistless vigor of youth to the impassive-ness of age. "It is not the crazy scheme you think it, Mr. Barrington," she said in that liquid voice which was an inheritance from her creole ancestry, "and I do not mean to risk my last dollar. You know I have means that cannot be touched....

The Cumulative Index of Systems Reviewed in the Chemistry of Heterocyclic Compounds is a collection of data for the approximately 2700 systems reviewed therein that serves as a useful guide to locating information in this well established and reputable series. The Cumulative Index also contains a complete list of books in the series showing author(s), title, date of publication, and all chapter headings. It is useful to professionals and advanced graduate students in synthetic organic chemistry, in academia, government, and industries including pharmaceuticals, fine chemicals, and agriculture.

We're going to have snow to-night! Ted Strong, leader of the broncho boys, was sitting on the back of Sultan, his noble little black stallion, on the ridge of a prairie swell, looking at a lowering sky. Out of the northwest a chilling wind, damp and raw, was sweeping dull-gray clouds before it. Ted had addressed his remark to Bud Morgan, his chum and able lieutenant, who threw a glance at the clouds and grunted.
