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]
Pyridine N-oxide is five orders of magnitude less basic than pyridine: the pK a of protonated pyridine-N-oxide is 0.8. [7] 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 .

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 ...

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]
Ligroin is the petroleum fraction consisting mostly of C 7 and C 8 hydrocarbons and boiling in the range 90‒140 °C (194–284 °F). The fraction is also called heavy naphtha. [1] [2] Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha. [3]
