“…[49] The nitrogen-aluminium bond in these complexes was revealed to be impressively strong, since the addition of 3 equiv. of HBr led to the cleavage of the relatively weak Al-P bond to form [Cr-(CO) 5 [51] forms a six-membered ring dimer both in solution and in the solid state, as observed by NMR spectroscopy and X-ray diffraction studies. In the presence of a Lewis base (LB), it is possible, however, to break the cyclic dimer to form the monomeric Me 2 PCH 2 AlMe 2 ·LB.…”

“…[10] As as ubgroup of the intramolecular LPs, [1,[3][4][5]11] methylene-bridged Lewis pairs (BLPs) were already known for the activation of small molecules or for diverse catalytic purposes before the term "FLP" was introduced. [12,[13][14][15] Besides these applications,X ua nd Chen demonstrated that boron-phos- Figure 1. Top: Possible initiation pathways for the BLP-mediated polymerization of Michael-type monomers.…”

“…[13] In dem aus diesem ersten Experiment abgeleiteten sphärischen Atommodell (independent atom model, IAM) beobachteten wir eine deutliche Vergrçßerung des axialen Al1-C5-Abstandes (2.0091 (13) ) gegenüber dem äquatorialen Al1-C4-Abstand (1.9719- (16) ), verbunden mit einer erhçhten Restelektronendichte am axialen Kohlenstoffatom. Zuerst wurde die Molekülstruktur von Me 2 AlCH 2 PMe 2 (1)bei niedriger Te mperatur (100 K) erneut und mit hçherer Auflçsung (0.65 )a ls bei der erstmaligen Aufklärung 1985 bestimmt.…”

“…[10] Als Untergruppe der intramolekularen LPs [1,[3][4][5]11] waren Methylen-verbrückte Lewis-Paare (BLPs) bereits vor der Einführung des Begriffs "FLP" fürd ie Aktivierung kleiner Moleküle sowie fürd iverse Katalysen bekannt. [12,[13][14][15] Außerdem zeigten Chen und Xu, dass bor-und phosphorbasierte BLPs als hochaktive Katalysatoren fürd ie Polymerisation von g-Methyl-a-methylen-g-butyrolacton fungieren kçnnen, jedoch den Nachteil von breiten Dispersitäten mit sich bringen. [16] Die Cycloaddition der BLPs an das Monomer führt zu einem siebengliedrigen, zwitterionischen Ringzwischenprodukt als vorgeschlagene aktive Spezies,d ie bei der Te rmination gespalten wird.…”
