In the case of oxidative addition-induced reactions, some feasible examples aiming at synthesizing chiral indanes, indolines, dihydrobenzofurans, benzocyclobutenes, and lactams will be developed from readily available aryl or alkenyl
halides or triflates.
substituent (1-methylethenyl) resulted in increased antibacterial activity, as seen in limonene [1-methyl-4-(1-methylethenyl)-cydohexene], compared to an alkyl (1-methylethyl) substituent as in p-cymene [l-methyl-4-(1-methylethyl)-benzene].
BASF has obtained a patent for a n aqueous coating formulation comprised of a substituted, branched polyethyleneimine, which is obtained by a process comprised of reacting a branched polyethyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative of formula (I) R--(C=0)X (I), wherein R is a C5 to C18 alkyl group or a C5 to C18 alkenyl
group, X is a halogen, a hydroxyl group, or a group R--(C=0)--O--, a molar amount of the carboxylic acid derivative in the reacting is from 3 to 10 mol percent of a molar amount of ethyleneimine employed in preparing the branched polyethyleneimine, the reacting is comprised of formation and removal of a byproduct HX, and the formulation is configured to coat a substrate that is comprised of tannin.
In the Chinese market, polyether monomers mainly include polyethylene glycol monomethyl ether (MPEG), allyl polyoxyethylene ether (APEG) and methyl alkenyl
polyoxyethylene ether (TPEG).
The graft copolymer is prepared by graft-polymerizing an aromatic alkenyl
and a vinyl cyanide onto a rubber polymer.
The co-ctystallizing agent is selected from the group consisting of fatty acid having a C16-22 alkyl, alkenyl
, alkylaryl or alkoxy moiety; fatty alcohol having a C16-C22 alkyl, alkenyl
, alkylaryl or alkoxy moiety; and mixtures thereof.
The mild conditions required for hydrolysis and condensation of alkoxysilanes allow an enormous number of substituents (alkyl, aryl, alkenyl
2 (m, 10H, aromatic protons & alkenyl
R2 is H or an alkyl, alkenyl
, cycloalkyl, or aryl group, optionally having 1-3 substituents independently selected from the group consisting of C1-C6alkyl, OH, O--C1-C6alkyl, halogen and CF3.
To our knowledge there is no information about the alkenyl
chain composition in marine gastropods although in two freshwater prosobranchs, Misra et al.
In Part I of this book, Levashova (Sterlitamak State Pedagogical Institute, Russia) and Zaikov (biochemical physics, Russian Academy of Sciences, Russia) detail the synthesis and properties of alkenyl
aryl esters and N-alkenyl
-substituted amines, and in Part II, they describe a process for utilization of methallyl chloride production wastes and synthesis of small-tonnage chemical products from them.
