The Reduction of Carbonyl Compounds by Sodium Naphthalenide
… of sodium naphthaienide with various aromatic carbonyl compounds, particularly aromatic aldehydes and ketones. Although sodium naphthalenide was first investigated in 1936 by Scott et al, the synthetic utility of this alkali metal adduct in organic chemistry has only recently been explored. It …

Some chemistry of Group IVB-cobalt carbonyl compounds
… depending on the ratio of the reactants. Decarbonylation of a mixture of Me₂Ge₂Co₄(CO)₁₄, MeGeCo₃(CO)₁₁ and MeGeHCo₂(CO)ₓ produced a small amount of (MeGe)₂Co₄(CO)₁₁ together with a new compound Me₃Ge₃Co₅(CO)₁₄ (or (MeGe)₂Co₄(CO)₁₀(μ-Ge(Me)Co(CO)₄)) which was characterised by a full crystal …

Ligand-bridged dinuclear carbonyl compounds of rutheniun and osmium
Ligand-bridged dinuc1ear carbonyl compounds of ruthenium and osmium have been successfully prepared and characterised by various analytical and spectroscopic techniques. X-ray crystal structures have been determined for the osmium complexes [OS2(CO)4(p-02CCsH4FeCsHs)2L2] {L = PPh3 (102), py (103)}. …

The Reactions of Sodium Naphthalenide with Carbonyl Compounds and Esters
… reactions of sodium naphthalenide with various carbonyl and acyl compounds. J. W. Stinnett, Jr. investigated aspects of the reactions of carbonyl compounds and that study was expanded. The major emphasis, however, was to extend the investigation to the reactions of esters. With regard to the …

Photoredox activation of carbon dioxide and unactivated aliphatic carbonyl compounds
Chapter 1: Photoredox Activation of Carbon Dioxide for Amino Acid Synthesis in Continuous Flow. Although carbon dioxide (CO₂ ) is highly abundant, its low reactivity has limited its use in chemical synthesis. In particular, methods for carbon-carbon bond formation generally rely on two-electron …

Preparation and reactions of some organic derivatives of manganese carbonyl compounds
… including some in which the donor ketone carbonyl group is incorporated into a fused ring. Analogous derivatives of benzoates and heteroaromatic carboxylic acid esters are also described, together with several orthorheniated compounds. Single crystal X-ray structure determinations of …

Competing reaction pathways in the photochemical reactions of metal carbonyl compounds
The photochemical reaction of Mn$\sb2$(CO)$\sb{10}$ with HSnBu$\sb3$ has been studied by continuous photolysis. Sunlamp irradiation of a CO-saturated hexane solution of Mn$\sb2$(CO)$\sb{10}$ and HSnBu$\sb3$ results in formation of HMn(CO)$\sb5$ and Bu$\sb3$SnMn(CO)$\sb5$ in equimolar quantities. …

Intermolecular [3+2] Cycloadditions of Imino-isocyanates to Access β-Amino Carbonyl Compounds
… In this regard, the synthesis of β-aminocarbonyl compounds from alkenes remains a long-standing challenge. Innovation in reaction discovery often requires finding new reagents, or rare reagents with underappreciated value in synthesis. In Chapter 1, N-isocyanates and other heterocumulenes …

The elucidation of single electron transfer (SET) mechanisms in the reactions of nucleophiles with carbonyl compounds
… and nucleophiles known to react via SET with carbonyl compounds, 20 successfully produced products characteristic of SET pathways. However, subsequent studies of the reaction between <b>20</b> and thiophenoxide, a nucleophile purported to undergo SET, produced no evidence for a SET pathway. It …

Borylations and Silylations of Alkenyl and Alkynyl Carbonyl Compounds Employing a Mild and Environmentally Friendly Cu(II) Catalyst
An environmentally friendly, operationally simple copper-amine catalyst system is disclosed. Using this catalyst system, electron deficient alkenes and alkynes with diverse functional groups are borylated and silylated in high yields and with short reaction times. In the case of electron deficient …
