All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
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]
Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C).
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 ...

Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.
For instance, the cavity of cucurbit[6]uril has a height ~9.1 Å, an outer diameter ~5.8 Å, and an inner diameter ~3.9 Å. [ 1 ] Cucurbiturils were first synthesized in 1905 by Robert Behrend , by condensing glycoluril with formaldehyde , [ 2 ] but their structure was not elucidated until 1981. [ 3 ]
4,4′-Dichlorodiphenyl sulfone (DCDPS) is an organic compound with the formula (ClC 6 H 4) 2 SO 2. Classified as a sulfone , [ 1 ] this white solid is most commonly used as a precursor to polymers that are rigid and temperature-resistant such as PES or Udel.
