Isopropyl sulfide

Reductive Thiolation. Treatment of aldehydes with triethylsilane, thiols, and boron trifluoride monohydrate 217 yields sulfides in a one-flask process. For example, this method gives a 97% yield of benzyl isopropyl sulfide from benzaldehyde and 2-propanethiol (Eq. 204).365... [Pg.74]

Interpretation I report Ethyl isopropyl sulfide is the off-flavor compound and its source is the polypropylene packaging material. [Pg.828]

Was it important to know quantitatively the amount of ethyl isopropyl sulfide, or just its presence above a threshold level ... [Pg.831]

The solid state structures of methylzinc fert-butyl sulfide , methylzinc isopropyl sulfide and ethylzinc ethyl sulfide have been determined. All are aggregated clusters. Methylzinc tert-butyl sulfide is a pentamer (MeZnSBu-t)5 in which four of the sulfide groups are /r -bonded to four zinc atoms and one sulfide is /r -bonded between two zinc atoms (Figure 108). Consequently, four of the zinc atoms have a distorted tetrahedral geometry while the remaining zinc atom is trigonal planar. [Pg.120]

Methylzinc isopropyl sulfide is an octamer (MeZnSPr-Og in which all the sulfide groups are -bridge-bonded to three zinc atoms, rendering them all distorted tetrahedral. No further details are given for this structure. [Pg.120]

SYNTHESIS To a solution of 2.5 g of KOH pellets in 40 mL hot EtOH, there was added 5.4 g 2,5-dimethoxythiophenol (see under 2C-T-2 for its preparation) and 8.7 g isopropyliodide. White solids appeared in a few min, and the reaction mixture was heated on the steam bath overnight. This mixture was added to 200 mL H20 followed by additional aqueous NaOH to raise the pH to a deep purple-blue on universal pH paper. This was extracted with 3x75 mL CH2C12. The pooled extracts were stripped of solvent under vacuum, and the residue distilled at 100-110 °C at 0.2 mm/Hg to yield 6.9 g of 2,5 -dimethoxyphenyl isopropyl sulfide as a pale yellow... [Pg.291]
