References Added in Proof

The following references extend the literature coverage up to December 31, 1975. The preparation of derivatives of one previously unknown type A meso-ionic system has come to the attention of the authors since the completion of the Appendix. These new meso-ionic compounds are l,2,3-thiadiazole-5-ones [Table A-I (page 111) a = S, b = N, c = NR, d = CR, e = C, f = O]. They are the first examples of sulfur analogs of the sydnones (1).

Isotope Exchange of Deuterated Thienothiophenes Quantum-Chemical 

Further Chemical Reactions and Possible Applications of the Isomeric Thienothiophenes 

The present review deals with condensed systems of heteroaromatic five-membered rings—thienothiophenes, di enothiophenes, seleno-phenoselenophenes, and selenophenothiophenes. The number of publications devoted to such compounds has grown rapidly in recent years. This is indicative of the mounting interest in various aspects of this field of heterocyclic chemistry, which, however, has not been reviewed since the 1954 monograph of Hartough and Meisel.

Homogeneous Hydrogenation Catalyzed by Cobalt Cyanide Complexes. 433 

These complexes may be either six-coordinate with an octahedral configuration or five-coordinate with a square-pyramidal configuration, in which the organo ligand occupies the apical position a few form dimers through the interaction of each cobalt with a coordinated atom of the equatorial ligand of the other half (see Section In virtually all groups 

The main aim of this review is to survey the reactions by which the Co—C bond is made, broken, or modified,.and which may be used for preparative purposes or be involved in catalytic reactions. Sufficient evidence is now available to show that there exists a general pattern of reactions by which the Co—C bond can be made or broken and in which the transition state may correspond to Co(III) and a carbanion (R ), Co(II) and a radical (R-), Co(I) and a carbonium ion (R ), or a cobalt hydride (Co—H) and an olefin. Reactions are also known in which the organo ligand (R) may be reversibly or irreversibly modified (to R ) without cleavage of the Co—C bond, or in which insertion occurs into the Co—C bond (to give Co—X—R). These reactions can be shown schematically as follows  

Certain groups of organocobalt(III) complexes have been dealt with in previous reviews. The organo-corrinoids have been mentioned in all reviews on vitamin B, 2 since 1961, when the coenzyme form was identified as an organometallic compound [see, for example, (79, 178) and references therein]. The literature on the corrinoids is too extensive to be treated comprehensively here and for details and references readers are referred to the book on The Inorganic Chemistry of Vitamin B,2 (136)certain other aspects of the organometallic chemistry of cobalt corrinoids are treated elsewhere (137). The pentacyanides were reviewed in 1967 (105), the DMG complexes (cobaloximes) in 1968 (145), and some aspects of salen, BAE, and related complexes in 1970 (17).

Appendix, we present tables summarizing the reactions that have been carried out with each metal vapor. For the sake of completeness, we have included a few types of reactions in which the products are not organometallic e.g., the formation of metal-phosphine and metal-acetyl-acetone complexes. Our review covers the literature up to February 1976 with selected references added in proof in December 1976. 

The purpose of this section, added in proof, is to include certain references inadvertently omitted in the initial preparation of this article, as well as to update the review. We consider the literature coverage to be complete to about July 31,1979. The papers referred to in this section will not be discussed in detail.

The unexpected overlap of this problem is more surprising than significant, for the first derivative of the effectiveness factor with respect to the Thiele modulus (Figs. 8 and 9) does not stand out as of particular interest.

Note added in proof. It was stated in Volume 14 of Photochemistry that Furusaki et had revised the structure of the photodimer of biphenylene which was originally reptorted by Goldman and Ruden. Professor Goldman has recently advised the Reporter that the revision of the structure had already been published in 1980 by Passer, White, Goldman, and Lerit it is regretted that this reference, which corrects the earlier report, was overlooked and not included in an earlier Volume in this series.
