Reaction of thiodiacetone alcohol with chlorides of trivalent phosphorus acids

Article abstract of DOI:10.1007/BF00922817

1. Thiodiacetone alcohol reacts with the monochlorides of trivalent phosphorus acids in the presence of a base to give tricoordinated phosphorus derivatives. 2-Ethoxy-2-thio-3,5,5-trimethyl-1,2-thia-3-phos-pholanol is formed in the case of ethyl dichlorophosphite. 2. The reaction of thiodiacetone alcohol with phenyldichlorophosphine in the absence of a base gives 2-phenyl-2-thio-1,2-oxa-3,3,5-trimethyl-4-phospholene.
