Hydroformylation – Homogeneous

Abstract

Transition‐metal‐catalyzed olefin hydroformylation in homogeneous systems is reviewed.

Regioselectivity of the borylation of alkanes and arenes

“…For example, hydrozirconation of an internal alkene gives rise to a terminal alkylzirconium complex as product, 44 and hydroformylation of internal alkenes with catalysts that are capable of reversible b-hydrogen elimination leads to terminal alkyl intermediates and ultimately linear aldehyde products. 45 Linear organosilanes have also been formed from internal alkenes during studies of nickel-catalyzed hydrosilylation. 46 These observations result from the isomerization of secondary alkyl complexes to primary alkyl complexes.…”

Isomerization–Hydroformylation Tandem Reactions

“…Tandem reactions bearing a hydroformylation step have been summarized in the literature a few times. , A most frequently cited article was written by Eilbracht et al in 1999 . Updates were published in 2004 and 2006 .…”

Followed by the Affected Compassion of the Free World. The 1956 Revolution from Different Perspectives

“…Western activities in support of the Hungarian Revolution greatly influenced Soviet leadership to take a stance in favor of Egypt, and to play a decisive role in resolving the Suez Crisis. (…) Minister of Foreign Affairs Shepilov 75 issued a letter to the Chairman of the Security Council, while Prime Minister Bulganin 76 sent telegrams to Eden, 77 Mollet, 78 and Ben-Gurion, 79 in which he threatened all three countries with the deployment of missile weapons. This had a serious and positive effect on Arab public opinion.…”

“…Lindt had expressed these intentions as early as the height of the refugee crisis at the 10 January 1957 session of the Co-ordination Committee in Geneva, stating that "he wished to express the hope that the great upsurge of public sympathy and interest in the refugees which had been caused by the Hungarian crisis, could be kept alive and extended to those unfortunate 'old' refugees, many of whom had been living for ten years in refugee camps waiting for the chance of a new life." 79 To this end, the UNHCR took definite steps in co-operation with other actors of the refugee relief system.…”
