In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Spiranes. X. 2,2′,3,3′-Tetrahydro-3,3′-spirobis[4H-1,5-benzo-oxathiepine]. Topological equivalency of the diastereoisomers, published in 1973, which mentions a compound: 3229-00-3, mainly applied to spirobisbenzooxathiepine conformation; NMR spirobisbenzooxathiepine; cycloaddition tetrabromoneopentane monothiocatechate, Computed Properties of C5H8Br4.
The title compound (I) was prepared (2%) by heating a Cellosolve solution of o-NaSC6H4ONa with C(CH2Br)4 in sealed glass tube for 100 hr at 160°. The structure of the product was confirmed by ir, uv, and NMR spectra. The preferable conformations were determined by NMR.
There are many compounds similar to this compound(3229-00-3)Computed Properties of C5H8Br4. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
