Thermoelectric material, one of the new energy materials, is regarded as one of the most important energy-saving materials, which can directly achieve the interconversion between heat and electricity. Since its discovery and wide application, organic thermoelectric materials have attracted wide attention over the past several decades. The applications of organic thermoelectric materials have shown numerous advantages such as low-cost fabrication, facile processability, light weight, and flexibility. In particular, the past several years have witnessed remarkable progress in organic thermoelectric materials and devices. In this chapter, we will focus on various conducting polymers, such as polyacetylene (PA), polyaniline (PANi), polypyrrole (PPy), polythiophene (PTh), poly(3,4-ethylenedioxythiophene) (PEDOT), polycarbazoles (PCz), polyphenylenevinylene (PPV), and their derivatives, as well as D-A type polymers with a low bandgap, metal-organic coordination polymers and some semiconductors based on small molecules, which have been developed and investigated on thermoelectric performance. Various strategies for the synthesis of these organic thermoelectric materials are discussed in detail and their thermoelectric properties are summarized. Prospects and suggestions with respect to future research and development are also concluded with the authors’ outlook.

Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C52H43Cl3O3Pd2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52522-40-4

The first de novo construction of enantioenriched dihydroquinazolinones via an intermolecular strategy has been established. This approach also represents the first catalytic asymmetric [4+2] cycloaddition of vinyl benzoxazinanones with sulfonyl isocyanates, which afforded chiral dihydroquinazolinones in high yields and excellent enantioselectivities (up to 98% yield, 99:1 er). This reaction not only confronts the great challenge in de novo construction of enantioenriched dihydroquinazolinone skeletons, but also advances the chemistry of decarboxylative cycloadditions involving vinyl benzoxazinanones.

The reactions of SiHPh(NCH2PPh2)2C6H4-1,2 with a range of zerovalent group 10 reagents afford the homoleptic bimetallic complexes [M2{mu-kappa3-Si,P,P?-SiPh(CH2PPh2)2C6H4}2] (M = Ni, Pd, Pt) in which the M-M bond is unsymmetrically bridged by two sigma-silyl groups. The asymmetry of the M2Si2 core increases from Ni through Pd to Pt and is consistent with a bonding description in which one metal acts as an electron pair donor to a trigonal bipyramidal ‘Z-type’ silicon centre, reminsicent of semi-bridging coordination by CO, carbynes and boryl ligands.

A catalytic reductive coupling method has been developed whereby 2- and 3-bromo- and 2-iodothiophenes, 2-bromothiazole and 2-bromofuran are converted into their corresponding bithiophene, bithiazole and bifuran derivatives. The use of a basic alcohol medium favours the reductive coupling pathway over the hydrodehalogenation pathway, which is generally more facile when other reducing agents are used. The catalytic mechanisms are discussed. The syntheses and characterization of the proposed intermediate complexes, trans-[PdBr(C4H3S-C)(PPh3)2] 1, trans-[PdI(C4H3S-C)(PPh3)2] 2 and trans-(N,P)-[{PdBr(mu-C3H2NS-C2,N)(PPh 3)}2]·1/2CHCl3 3 support the proposed mechanism and the catalytic results. Single-crystal X-ray crystallographic structure determinations of 2 and 3 were carried out.

After decades of development, carbonylation reactions have become one of the most powerful tools in modern organic synthesis. However, the requirement of CO gas limits the applications of such reactions. Reported herein is a versatile and practical protocol for carbonylative reactions which rely on the cooperation of phenyl formate and nonaflate, and the generation of CO in situ. This protocol has a high functional-group tolerance and could be applied in carbonylations with C, N, and, O nucleophiles. The corresponding amides, alkynones, furanones, and aryl benzoates were synthesized in good yields.

In the presence of a Pd(ii)/P-ligand catalytic system, decarboxylative alkynylation of alkynyl carboxylic acids and arylsulfonyl hydrazides by desulfinative coupling could provide aryl alkynes in satisfactory yields by either judiciously selecting palladium catalysts or modulating phosphine ligands under mild conditions. The reported coupling reactions are very practical as they do not require the protection of inert gas or oxygen and are tolerant to many functional groups.
