The first total synthesis of was successfully established via steps and conditions several crucial were optimized ensure smooth operations. Given the everexpanding literature is becoming increasingly more time consuming to maintain comprehensive tradition of last four editions. However approximately new references have been included this edition [...]
Sulfinic acids are weaker having pKa of roughly.

The central sulfur in sulfuranes is described as being part of threecentre fourelectron bond [...]
Acid triflic CFSOH one of the strongest known organic acids is manufactured by electrochemical fluorination methanesulfonyl chloride fluoride and used as polymerization catalyst fuel cells gasoline production synthesis organometallic compounds. Sulfonic acid groups can greatly enhance the water solubility of compounds as seen with derivative triphenyl phosphine TPPTS CHm SONa. Thank you for your feedback editors will review what ve submitted and determine whether revise article. This discovery led to the development of sulfa drugs which still find some use today treatment infections although they have been largely replaced by newer antibiotics bacteria are less resistant [...]
