I've moved this topic from Citizen Chemist here to Organic Chemistry, and I hope you'll get the help from our regulars. Some caveats I'd like to mention however.
It seems like you're making organic selenides. Its an interesting concept to be sure. You're a little unsure of some of the techniques, and we're here to help. However, we can't teach you organic chemistry laboratory techniques with forum postings. You need the very basics of laboratory chemistry from school, and to understand some basics of synthetic organic chemistry. So you'll have to bear with us if we're too general for you to just make this stuff.
A little Googleing tells me you may have read a patent from someone who suggests that this is a cancer medicine. We don't mind helping a person learn some techniques, but we won't help you self-medicate, for liability reasons. So I hope we can keep this thread theoretical.
