Organometallic diazo compounds
Chemical Reviews, 1993Organometallic chemistry has traditionally, by definition, been concerned with the chemistry of metalcarbon-bonded compounds. Nevertheless, there is growing interest in metal-heteroatom bonds such 88 M-N, M-O, M-S, etc., in organometallic compounds.

New Syntheses of Diazo Compounds
Angewandte Chemie International Edition, 2009AbstractDiazo compounds (R1R2CN2) are known as versatile and useful substrates for an array of chemical transformations and, therefore, diazo chemistry is still far from losing anything of its long‐standing fascination. In addition to many studies on the subsequent chemistry of the diazo group, the inventory of methods for the preparation of diazo ...

Abstract Reaction of α-diazo ketones,RCOCN2R', with boiling carbon disulfide can give two major types of product: 2-alkylidene-1,3-dithiolan-4-one derivatives (Type A) and 4-acyl-2-alkylidene-1,-3-dithetane derivatives (type B). When R' = phenyl and R = phenyl or methyl, type A but not type B products are formed.

Chemistry of Heterocyclic Compounds, 1974
Benzothiazole-2-diazonium tetrafluoroborate and its 6-bromo, 6-methyl, and 6-methoxy derivatives are relatively stable and have high electrophilicities. They are rapidly converted in weakly alkaline media to the corresponding anti-diazotates, from which primary nitrosoamines can be obtained by acidification.

How Nucleophilic Are Diazo Compounds?
Chemistry – A European Journal, 2003AbstractThe kinetics of the reactions of benzhydryl cations with eight diazo compounds 1 a–g were investigated photometrically in dichloromethane. The nucleophilicity parameters N and slope parameters s of these diazo compounds were derived from the equation log k (20 °C)=s (E+N) and compared with the nucleophilicities of other π systems (alkenes ...
