Exempel på hur man kan använda ALKOXY i en mening

• The Greek prefix hèmi means half, refers to the fact that a single alcohol has been added to the carbonyl group, in contrast to acetals or ketals, which are formed when a second alkoxy group has been added to the structure.
• Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group, most commonly from carboxylic acids and alcohols.
• There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups.
• any substance that has a 1-amino-2-phenylethane structure substituted at the 2' and 5' or 2' and 6' positions of the benzene ring by an alkoxy or haloalkoxy group, or substituted at two adjacent carbon atoms of the benzene ring which results in the formation of a furan, dihydrofuran, pyran, dihydropyran or methylenedioxy group—whether or not further substituted on the benzene ring to any extent, whether or not substituted at the amino group by one or two, or a combination of, methyl, ethyl, propyl, isopropyl, hydroxyl, benzyl (or benzyl substituted to any extent) or benzylene (or benzylene substituted to any extent) groups and whether or not substituted at the 2-ethyl (beta carbon) position by a hydroxyl, oxo or alkoxy group—and its salts and derivatives and salts of derivatives, including:.
• The crosslinkers used in condensation cure systems are typically alkoxy, acetoxy, ester, enoxy or oxime silanes such as methyl trimethoxy silane for alkoxy-curing systems and methyl triacetoxysilane for acetoxy-curing systems.
• Another class of compounds called phosphazenes are represented with the formula , where X = halogen, alkoxy group, amide and other organyl groups.
• During research and development, pramocaine hydrochloride stood out among a series of alkoxy aryl alkamine ethers as an especially good topical local anesthetic agent.
• They have successfully demonstrated catalysis of the ortho-alkylation of aromatic ketones, alkyl aldehyde isomerization, hydroacylation, and the dehydrogenation of alkoxy silanes to generate silyl enol ethers.
• Cyc = any monocyclic, or fused-polycyclic ring system (not being a phenyl ring or alkylenedioxyphenyl ring system), including analogues where the ring system is substituted to any extent with alkyl, alkoxy, haloalkyl or halide substituents, whether or not further substituted in the ring system by one or more other univalent substituents.
• Stoichiometric reducing agents to accomplish this task include lithium aluminium hydride, sodium borohydride, alkoxy borohydrides, alkoxy aluminium hydrides, and boranes.
• However, the distinction is not always consistent throughout literature where organophosphorus compounds without the alkoxy sidechains or even with a O=S group instead of a O=P group are still classified as organophosphate pesticides (OPs).
• A trialkoxyborane can react with lithium containing organic molecules to eliminate lithium and one or two alkoxy groups to make boronic and borinic esters.
• Jacobsen at Harvard University and worked with then-graduate student Abigail Doyle to develop an enantioselective substitution of silyl ketenes onto an alkoxy chloride via an oxocarbenium ion using a novel thiourea organocatalyst.
