The invention relates to new furfurylthioalkanes of the formula ##STR1## wherein n can be zero or 1

Furfurylthioalkanes, a process for their preparation and their use

Use of 3-acylthiohexyl esters of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.5 -C.sub.12 -aryl, including furyl and thienyl, as aroma and/or odoriferous substances, and aroma and odoriferous substance compositions containing these compounds.

Use of 3-acylthiohexyl esters as aroma and odoriferous substances

Thioalkane .alpha.,.beta.-diketones have interesting organoleptic properties and are therefore suitable as aroma substances.

Use of thioalkanediones as aroma substances

Dimethylfuryl-dihydro-1,3,5-dithiazines are useful flavorings having low taste threshold values. They impart a coffee or mocha taste, in particular to drinks, confectionery and bakery products.

Dimethylfuryl-dihydro-1,3,5-dithiazines

The invention relates to new thio-alkanones of the formula ##STR1## in which X represents an oxygen or sulphur atom,

Thio-alkanones, process for their preparation and their use

New hemimercaptals of the formula ##STR1## in which X represents an oxygen or sulphur atom, a process for their preparation and their use as flavorings have been found.

Hemimercaptals, processes for their preparation, and edible compositions

Unsymmetrical dihydrodithiazines of the formula ##STR1## in which one of the substituents R.sub.1 and R.sub.2 represent a C.sub.3 -C.sub.5 -alkyl group while the other is a methyl group and R.sub.3 represents a hydrogen atom, or R.sub.1 represents a methyl group and R.sub.2 and R.sub.3 together form a C.sub.3 -C.sub.4 -alkylene radical, a process for their preparation and their use as fragrances and flavorings.
