Thioaldehydes, Thioketones, and Thioacetals

Thioaldehydes Rule C-531

531.1 - Where -(C)HS is the principal group the monomeric compound RCHS is named by adding "-thial" to the name of the hydrocarbon RCH3.

Example to Rule C-531.1

531.2 - Alternatively, the -CHS group is named "-carbothialdehyde" this term being used as suffix, the principles of Rule C-303.1 beingapplied.

Examples to Rule C-531.2

531.3 - Where -CHS is not the principal group, the prefix "thioformyl-" is used.

Examples to Rule C-531.3

531.4 - The use of "thio" and "aldehyde" in trivial names, as in "thiobenzaldehyde" (C6H5-CHS) is retained for simple instances, but the nomenclature of Rules C-531.1 to C-531.3 is in general preferred.
