Dienes overview

Excellent reviews on micelles formed in organic solvents have been published by Hamley [2], Chu et al. [86], and Riess [14]. From these overviews it appears that a wide range of styrene-, (meth)acrylates-, and dienes-based block copolymers were investigated and that the formation of micelles in organic solvents can generally be considered as an entropy-driven process. AB diblock and ABA triblock architectures were systematically compared. All these previous investigations have been summarized by Hamley [2], We will therefore not perform an extensive review of all these systems, since this information has already been provided by others, but we will briefly outline some selected examples. 

Abstract The basic principles of the oxidative carbonylation reaction together with its synthetic applications are reviewed. In the first section, an overview of oxidative carbonylation is presented, and the general mechanisms followed by different substrates (alkenes, dienes, allenes, alkynes, ketones, ketenes, aromatic hydrocarbons, aliphatic hydrocarbons, alcohols, phenols, amines) leading to a variety of carbonyl compounds are discussed. The second section is focused on processes catalyzed by Pdl2-based systems, and on their ability to promote different kind of oxidative carbonylations under mild conditions to afford important carbonyl derivatives with high selectivity and efficiency. In particular, the recent developments towards the one-step synthesis of new heterocyclic derivatives are described. 

To investigate the kinetics in more detail, the reaction rates of a simple pair of model compounds, [Pt(dien)X] [(X = Cl-, H2O) with GSH, GS-Me and 5 -GMP have been investigated and compared (164). The reaction products with GSH and GS-Me are shown in Fig. 10 an overview of the reactions between [Pt(dien)Cl] and GSH is presented in Scheme 2. These products are the first well-identified complexes between S-containing biomolecules and platinum amine compounds (130) and therefore are ideally suited as model compounds for kinetic studies. The results of the reactions are summarized in Table IV. In agreement with the above-mentioned hypothesis, the chloride hydrolysis is the rate-determining step in the reaction of [Pt(dien)Cl]+ with 5-GMP,...

In a recent extensive overview on the biotransformation of terpenoids by Aspergillus spp., Noma and Asakawa [92] also mentioned a sixth pathway of limonene bioconversion the hydroxylation at the C-4 position to give / -mentha-1,8-dien-4-ol (111), Fig. (20), a compound also identified earlier as one of the bioconversion metabolites of limonene with Penicillium italicum [83]. In this review, the fifth pathway, leading to isopiperitenol (113) which is further oxidised to isopiperitenone (112) and its rearrangement product, piperitenone (114) is also discussed.

Highly fluorinated alkenes are generally very electron-deficient species and therefore susceptible to attack by a wide range of nucleophiles. In this chapter we will attempt to give an overview of this chemistry, with emphasis of more recent work. The subject was reviewed many years ago [1] and other publications have included discussion of this subject [2-9]. We will also include some chemistry of fluorinated dienes, where appropriate.
