Thiol -2-butene

The mam components of a skunks scent fluid are 3 methyl 1 butanethiol and as- and trans-2 butene 1 thiol Write structural formulas for each of these compounds... [Pg.649]

Skunks deter predators by release of a liquid spray containing seven major volatile components classified as thiols (compounds containing the -SH functional group) and acetate derivatives of thiols (characterized by the SC(0)CH3 functionality). In particular, two of the more odiferous components responsible for the strongly repellent odor of the skunk s secretion are 2-butene-1-thiol (Fig. 13.2.1) and 3-... [Pg.169]

A characteristic of organic sulfur compounds, especially volatile (low molecular mass) thiols, is their disagreeable odors. For example, 3-methyl-1-butanethiol and 2-butene-1-thiol are ingredients of a skunk s perfume, and methanethiol or ethanethiol is usually added, in small amounts, to natural gas, which is odorless by itself, so that leaks can be readily detected. The chemical properties of thiols and sulfides differ from those of alcohols and ethers in that thiols are somewhat stronger acids than alcohols and the sulfur atoms of these compounds are considerably more nucleophilic than the oxygen of their analogs. They are excellent nucleophiles in substitution reactions. [Pg.489]

As shown in the case of l-octen-3-one in the beginning of this chapter, aroma-active compounds show an interesting indication as media in human-environment interactions the role of this often disliked compound has some similarity to alarm pheromones. Flavor or smell of food can be categorized into food attractant molecules from this point of view. Infants are able to recognize the body odor of their mother and are attracted to it.189 An opposite example is represented by the notorious ability of skunks to spray, in which thiol compounds such as (E)-2-butene-1 -thiol and 3-methyl-l-butanethiol are used as potent repellents190(see Chapter 4.09). [Pg.618]

The most obvious cheracteristtcofthiols is thmappallii odor. Skuitb for example, is caused primarily by the aimple UiMs 3-methyh 1 butonet j and 2-butene 1-thiol. Volacile thiols are also added to natural gas tos is> as an easily detectalde warning in case of leaks. [Pg.726]

The major (50%-75%) components of the malodorants in the skunk (Mephitis mephitis, Spilopgale gracilis, and Conepatus mesoleucus) defensive secretions are (E)-2-buten-1-thiol and 3-methyl-1-butanethiol. Other disulfides, thioacetates, and thiols are present in lesser amounts, and vary with species. In addition to the S-containing compounds, the alkaloid 2-methylquinoline has been identified in skunk secretions (Wood, 1990 Wood et al., 1991, 1993). Brief notes on examples of representative malodorants are given below. [Pg.369]

The odor of thiols is their strongest characteristic. Skunk scent is composed mainly of 3-methyl-1-butanethiol and 2-butene-1-thiol, with small amounts of other thiols. Ethanethiol is added to natural gas (odorless methane) to give it the characteristic gassy odor for detecting leaks. [Pg.452]

Authentic skunk spray has become valuable for use in scent-masking products. Show how you would synthesize the two major components of skunk spray (3-methylbutane-1-thiol and 2-butene-1 -thiol) from any of the readily availablebutenes or from 1,3-butadiene. [Pg.453]
