An expeditious synthetic strategy to access functionalized S-thiocarbamates was developed in good to excellent yields and with high current efficiencies. Readily available isocyanides and thiols were used as the starting materials under simple metal- and oxidant-free reaction conditions avoiding an inert atmosphere. The practical application of the present methodology was achieved by electrochemical synthesis of the herbicides prosulfocarb and pebulate. Furthermore, continuous electrochemical flow conditions using a graphite/Pt flow cell were used to obtain S-thiocarbamate compounds on a gram scale within a residence time of 35 min. This journal is

, (2008/06/13)
The invention relates to novel oxime ethers of the formula I STR1 wherein R1 is hydrogen, halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, lower alkylthio, lower haloalkylthio, lower alkylsulfinyl, lower alkylsulfonyl, lower haloalkylsulfinyl, lower haloalkylsulfonyl or nitro, each of R2 and R3 is hydrogen, halogen, lower alkyl, lower alkoxy or lower haloalkoxy, and Q is an unsubstituted or substituted lower alkyl, lower alkenyl, lower alkynyl or cycloalkyl group, a lower alkanoyl radical, an aliphatic, cycloaliphatic, aromatic or heterocyclic acyl radical which may be substituted or unsubstituted, a carbonyl or thiocarbonyl radical, an aryl or aralkyl radical, an acylimidomethyl radical, a phthalimidomethyl radical or a heterocyclic radical. These compounds are able to act as antidotes or safeners for protecting cultivated plants from the phytotoxic action of aggressive herbicides. Preferred crops are sorghum, cereals, maize and rice, and herbicides are chiefly chloroacetanilides and thiocarbamates.

, (2008/06/13)
When applied as safeners, the haloacylaminoalkylphosphinates, haloacylaminoalkylphosphinates and haloacylaminoalkylphosphine oxides of the formula I below are able to protect cultivated plants from the phytotoxic effects of herbicides. Suitable crops are preferably sorghum, cereals, rice, maize and soya beans and the herbicides employed are chloroacetanilides and thiocarbamates. The haloacylaminoalkylphosphonates, haloacylaminoalkylphosphinates and haloacylaminoalkylphosphine oxides have the formula I STR1 wherein R1 is C1 -C4 alkyl, C1 -C4 alkoxy, C2 -C4 alkenyloxy, C2 -C4 alkynyloxy, C1 -C4 haloalkyl, C2 -C8 alkoxyalkoxy or C1 -C4 cyanoalkoxy, R2 is hydrogen or a substituent as defined for R1, R3 and R4 are each independently hydrogen, C1 -C4 alkyl or one of R3 and R4 is also a radical STR2 or both taken together with the carbon atom to which they are attached are also a C3 -C11 cycloalkyl radical, R5 is hydrogen, C1 -C4 alkyl, C3 -C7 cycloalkyl, C2 -C4 alkenyl, C2 -C4 alkynyl, C2 -C8 alkoxyalkyl, C1 -C4 haloalkoxy or aralkyl, R6 is hydrogen or C1 -C4 alkyl, X1 and X2 are each independently halogen or one of X1 and X2 is also hydrogen, and n is 1, 2 or 3.
