Reaction of (RP)- and (SP)-tert-butylphenylphosphinobromidates and tert-butylphenylthionophosphinochloridates with metallated phenol and BINOL alkoxides, thioalkoxides, amides and enolates leading with clean inversion at phosphorus to phosphinates, phosphinothiolates and phosphinoamidates, and the corresponding thionophosphorus compounds are described.
diastereoisomeric complexes with (+)-(R)-1,1′-binaphthalene-2,2′-diol and (+)-(S)-mandelic acid. With the latter complexing agent, separation of the essentially enantiopure (−)-(S)-enantiomer was achieved in a single complexation process. Addition of paraformaldehyde to this enantiomer gave α-hydroxymethyl-t-butylphenylphosphine oxide with high stereoselectivity and retention of configuration at phosphorus
Reaction of thiolo and selenolo esters of phosphorus acids with halogens. 1. Stereochemical and phosphorus-31 NMR studies of reaction of S-methyl tert-butylphenylphosphinothiolate with elemental chlorine and sulfuryl chloride
