In organic chemistry, thioketenes are organosulfur compounds analogous to ketenes with the general formula R2C=C=S, where R is alkyl or aryl. The parent thioketene (ethenthione) is has the formula CH2=C=S. It is the simplest thioketene. Thioketene is stable as a gas, but like most thioketenes, it polymerizes upon … See more Thioketenes can be stabilized by either steric protection or by electronic effects. Thus, di-tert-butylthioketene is easily isolated and air-stable. Several examples have been characterized by X-ray crystallography. … See more Thioketenes are electrophilic. They add amines to give thioamides: R2C=C=S + HNR'2 → R2CH−C(S)−NR'2 With peroxyacids, they produce thioketene-S-oxides: See more • carbon subsulfide (S=C=C=C=S). It has been suggested that thioketene could be involved in cell damage processes.

[1] They are analogous to allenes, only having a more extensive chain. The simplest molecule in this class is butatriene ( H2C=C=C=CH2 ), which is also called simply cumulene.
