The unique alumophosphite reagent LAl(SH)(-O)P(OEt)2 was prepared and used for the synthesis of theheterobimetallic alumophosphites [{2-S,P-LAl(S)(-O)P(OEt)2}2Zn] and [{4-S,O,O-LAl(SLi)(-O)P(OEt)2}2]. Thefirst contains a rare example of two carbon-free five-membered heterocycles (Al-S-Zn-P-O) connected in a spirofashion through the zinc atom, whereas the second possesses an unknown example of a coordination environmentof a phosphite unit M-O-P(-OEt)2M with an uncoordinated lone electron pair on the phosphorus center.
