Article Tin(II) compounds as synthetic control elements in organic synthesis was published on January 1, 1986 in the journal Pure and Applied Chemistry (volume 58, issue 4).
life on Earth has been referred to as "carbon based" because of the prevalence of carbon in forming essential compounds for organisms. Carbon is so prevalent in organic compounds because of its ability to form up to six stable bonds with other atoms; as a result, carbon is often in the ...
