Metallorganische Derivate des Acetylens. IV. �ber einige Alkyl?Bor-Acetylene
摘要:
AbstractDie Darstellung und die Eigenschaften von Bis‐(dialkylbor)‐acetylenen werden beschrieben. Eine Reihe von Dialkylborjodiden und Dialkylborsäuren wird erstmalig dargestellt und charakterisiert. Die Eigenschaften der dargestellten Verbindungen sind typisch für gemischte organische Borine, deren herausragende Eigenschaft die Neigung zur Bildung gleichartig substituierter Borine ist.
cis-2-Alkylcyclohexanols are obtained stereoselectively upon irradiation of a mixture of cyclohexene and the corresponding trialkylborane in the presence of p-xylene as a sensitizer and upon the successive oxidation of the photolysate with alkaline H2O2. The similar reaction of 1-ethylcyclohexene yields 2,2-dialkylcyclohexanols. Cycloheptene also reacts with the boranes to afford cis-2-alkylcycloheptanols
在对二甲苯作为敏化剂的存在下,对环己烯和相应的三烷基硼烷的混合物进行辐照,然后用碱性H 2 O 2连续氧化光解产物,可通过立体选择获得顺式-2-烷基环己醇。1-乙基环己烯的类似反应产生2,2-二烷基环己醇。环庚烯还与硼烷反应以提供顺式-2-烷基环庚醇。通过假定高度应变的反式-环己烯或-庚烯为反应性物质来解释这些反应。光化学产生的反式-环-辛-2-烯酮和顺式,反式-环-辛基-2,7-二烯酮与硼热反应,分别得到3-烷基环辛酮和顺式-7-烷基环辛-2-烯酮。cr啶与硼烷的光反应导致还原性烷基化,以相当好的收率得到9-烷基ac啶。

Treatment of lithium trialkylalkynylborates (1) with methanesulphinyl chloride gives internal acetylenes (2) in good yields. The reaction proceeds via β-methanesulphinylvinylboranes 3, followed by cis elimination of methanesulphinyl group and dialkylboron groups. The reaction mixture of B-alkyl-9-BBN and 1-lithio-1-heptyne has been treated with methanesulphinyl chloride to provide mainly a cyclooctane

tmp−B(SnPh3)−NHtBu was formed showing an umpolung of the hydrostannylation. Organyllithium compounds provide access to N-lithiodiaminoboranes of the type tmp−BR−NtBu−Li. The stability of these compounds depends on the substituent R. The least stable compound was the B−tBu derivative followed by the B-methyl compound. However, in the presence of TMEDA tmp−BMe−NtBu−Li is sufficiently stable to allow reactions
