Hallo !
I read eleusis document eleuisos, about isomerization of safrole : boling it whith CaO and KOH, alleged reference CA 47 art. 9360.
I tried to perform this reaction. failing several times (incomplete isomerization).
I read in several post on the hive that this method is ineffective, plus, looking for references I found something totally unrelated to isosafrole : some info about a german patent (see above).
Who know more ?
Are eleusis docs unfounded ?
CA 47 art 9360

Abstract
S-contg. org. compds. of the general formula RX.CS.S.R".S.CS.XR' (where X is S or O; and R and R' are aliphatic, cycloalifatic, aromatic or heterocyclic radicals; R" is an alkyl, cycloalkyl, aryl,
arakyl or heterocyclic group) useful as softening agents in the laquer industry, are prepd. by treating alkali-metal xanthenates or the corresponding tri-thiocarbonates with halo compds. contg. at least 2 Cl atoms bound to C atoms, preferably in aq. soln. or in water contg
org. solvents heating of iso-AmOCS2K 1010 in water 200 and
tetrahydrofuran (I) 800 with (CH2Cl)2 247 for 10 hrs at about 80, and removing I by distn. and the salts by washing with water gives as residue ethylene bis (isoamylxanthate) 790 parts. 1,4-(Butanediol bis(ethylxantate) is similary prepd from EtOCS2K and Cl(CH2)4Cl.
