I find that most syn.on the site, as you decribed to be very flawed, and barely work.(Even though most come from vogel practial chemistry book. I do however find most syn. found from schools, and University to work most of the time. By the way I meant oxidation. The reason for this is because they do the same syn. year after year, and correct any mistakes on the way. Have you ever went to a university? ADDkid
