Description
Известен способ получени трналкнларилацетиленилстаннанов взаимодействиелг метокситриалкилстаннанов с арилацетнлеиамп прп нагревании. При известном способе примен ли труднодоступные и токсичные исходные продукты.A known method for the preparation of trnalklaryl acetylenylstannanes is the interaction of methoxytrialkylstannans with arylacetylene by heating. In the known method, hard-to-reach and toxic starting materials were used.
Предлагаетс способ получени триалкиларилацетиленилстаннанов , отличающийс от известного тем, что гексаалкилдистаниоксиды взаимодействуют с арилацетиленами нри нагревании до 100°С.A method for the preparation of trialkylaryl acetylenylstannanes is proposed, which differs from the known one in that the hexaalkyl distanioxides interact with aryl acetylenes when heated to 100 ° C.
Пример. Синтез триэтилфенилацетиленилстаннана .Example. Synthesis of triethylphenylacetylenilstane.
В трехгорлую КОлбу, снабженную механической мешалкой, обратным холодильником и термометром, помещают 10,21 г (0,1 моль фенилацетилена и 10,68 г (0,025 моль) гекса .этилдистанноксида, т. кип. -110-112°С/1 мм, По 1,4987. Реакционную смесь нагревают при перемешивании 1 час при 100°С, затем10.21 g (0.1 mol of phenylacetylene and 10.68 g (0.025 mol) of ethyl distant oxide, kip. -110-112 ° С / 1 mm) are placed in a three-necked Kolba equipped with a mechanical stirrer, a reflux condenser and a thermometer. , According to 1.4987. The reaction mixture is heated with stirring for 1 hour at 100 ° C, then
перегон ют в вакууме. В результате перегонки выделено вещество с т. кип. 119-120°С/ 2 лш, пд 1,5555, df 1,2480, выход 78%, что соответствует триэти л фенил ацетил енилстант . кип. 120-122°С /2 мм:, по 1,5558,distilled in vacuo. As a result of distillation, a substance with m. Bale was isolated. 119-120 ° C / 2 lsh, pd 1.5555, df 1.2480, yield 78%, which corresponds to triethyl phenyl acetyl enylstant. kip 120-122 ° C / 2 mm: 1.5558,
