【Abstract】 Seven novel tri( n butyl)stannyl hydrogen alkynylphosphonate ( n C 4H 9) 3SnOP(O)(OH) C≡CR(R=Ph , n C 3H 7, n C 4H 9, n C 5H 11 , n C 6H 13 , CH 2OCH 3, CH 2OC 2H 5) were synthesized by the reaction of the monosodium salt of the alkynyl phosphanic acid with tri( n butyl)tin(Ⅳ) chloride. Their structures were characterized by means of elementary analysis, IR, 1H NMR and MS. The results showed that the tin(Ⅳ) atoms were five coordinted and bound together by virtue of the agency of —O—P—O? ?bridged polymers in these compounds.更多还原
