Purification of the dithioallene 26 on silica gel was difficult due to the ease of hydrolysis.

note
-
Dithio allenes are labile and difficult to be isolated; e.g., 1,1-bis(methylthio)-3,3-dimethyl-1,2-propadiene, which is prepared by the reaction of 1-lithio-3-chloro-3-methyl-1-butyne and dimethyl disulfide, is isomerized on silica gel into 1,1-bis(methylthio)-3-methyl-1,3-buta-diene, see ref 9a.
