and similarly (V) vinylcyclohexene, indane and indene were obtained from butadiene.ALSO:Olefinic compounds containing two or more double bonds and in which one or more unsaturated carbons may be bound to halogen, are prepared by heating an olefinic compound containing one or more double bonds with...
(A) an organic compound containing at least two carbon-carbon double bonds reactive with a SiH group in each molecule, (B) a silicon compound having at least two SiH groups in each molecule, (C) a hydrosilylation catalyst, (D) a silane coupling agent and/or an epoxy group-containing ...
The intensity of staining of each of four classes of neutral lipids (monoacylglycerol, diacylglycerol, triacylglycerol and fatty acid methyl ester) is shown to be dependent on the number or amount of carbon-carbon double bonds (C=C) when... CB Baron,RF Coburn - 《Journal of Liquid Chromatogr...
[2 + 2] Cycloaddition of two CN double bonds. First structural evidence for head-to-tail photodimerization in the 2-phenylbenzoxazole seriesphotochemistry, radiation chemistry, chemoluminescenceThe 2-arylbenzoxazoles (I) form the head-to-tail (2+2) cycloadducts (II) on photolysis in a two-...
athe two pairs of electrons of oxygen may be shared with one carbon alone forming a double bond, or with two separate carbons,or with one carbon and one hydrogen forming only single bonds 正在翻译,请等待... [translate]
The interaction between the residues and the base was weakened or eliminated by the migration of the monomers. DNA chains were more significantly twisted, and some bases could not be paired with each other (+1/+4). Lack of base-pairing and torsion of the DNA chains leads to an inability ...
Carbon dots have been gaining attention in the field of nanobiotechnology due to their superior photostability, high water solubility, ease of synthesis and surface functionalization, chemical inertness, low toxicity, and excellent biocompatibility. They also exhibit good two-photon absorption and unique ...
athe two pairs of electrons of oxygen may be shared with one carbon alone forming a double,or with two separate carbons,or with one carbon and one hydrogen forming only single bonds 二个对氧气电子也许分享与形成双的单独一碳,或者与二不同碳,或者与形成仅不附条件的债券的一碳和一氢 [translate]...
To provide more comprehensive evidence to the feasibility of this strategy, we chose two larger R groups (benzyl and naphthylmethyl groups), considering that the size of the butyl group might not completely rule out the possibility of its partial distribution in the small triangle pore. The incre...
Ideally, from a perspective of economy and sustainability, the conversion should include the direct functionalization of unactivated C(sp3)–H bonds. Here we introduce a methodology that enables the generation of complex cyclobutanes with up to four consecutive stereocentres, including all-carbon ...
