1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed] 1-Bromo-4-chlorobenzene: From a derivative of (4-bromophenyl)silane using N-bromosuccinimide [3] From 4-chlorophenol using triphenylphosphine dibromide [4] or phenylphosphorus tetrachloride [5]
Phenylsilane is produced in two steps from Si(OEt) 4. In the first step, phenylmagnesium bromide is added to form Ph−Si(OEt) 3 via a Grignard reaction. Reduction of the resulting Ph−Si(OEt) 3 product with LiAlH 4 affords phenylsilane. [2] Ph−MgBr + Si(OEt) 4 → Ph−Si(OEt) 3 + MgBr(OEt) 4 Ph−Si(OEt) 3 + 3 LiAlH 4 → 4 Ph−SiH 3 + 3 ...
Methylpyridinium is prepared by treating pyridine with dimethylsulfate: [2]. C 5 H 5 N + (CH 3 O) 2 SO 2 → [C 5 H 5 NCH 3] + CH 3 OSO − 3. It is found in some coffee products. [3] It is not present in unroasted coffee beans, but is formed during roasting from its precursor chemical, trigonelline. [3]
Protonated derivatives are isolable, e.g., [C 5 H 5 NOH]Cl. [3] Further demonstrating its (feeble) basicity, pyridine-N-oxide also serves as a ligand in coordination chemistry. A host of transition metal complexes of pyridine-N-oxides are known. Treatment of the pyridine-N-oxide with phosphorus oxychloride gives 4- and 2-chloropyridines. [8]
1,2-Diaminocyclohexane (DACH) is an organic compound with the formula (CH 2) 4 (CHNH 2) 2. It is a mixture of three stereoisomers: cis-1,2-diaminocyclohexane and both enantiomers of trans-1,2-diaminocyclohexane. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH.
Lilial (a trade name for lily aldehyde, also known as lysmeral or lilestralis) is a chemical compound commonly used as a perfume in cosmetic preparations and laundry powders, often under the name butylphenyl methylpropional.
3-Methyl-2-butanone (methyl isopropyl ketone, MIPK) is a ketone and solvent of minor importance. It is comparable to MEK ( Methyl ethyl ketone ), but has a lower solvency and is more expensive. [ 2 ]
JWH-018 is a full agonist of both the CB 1 and CB 2 cannabinoid receptors, with a reported binding affinity of 9.00 ± 5.00 nM at CB 1 and 2.94 ± 2.65 nM at CB 2. [6] JWH-018 has an EC 50 of 102 nM for human CB 1 receptors, and 133 nM for human CB 2 receptors. [16]
