Reactivity of frustrated Lewis pairs with BOC protected diazocarboxylates: FLP capture of diazene

Abstract

Reactions of (tBuO2CN)2 with FLPs are examined. B(C6F5)3 interacts with the carbonyl oxygen atoms inducing loss of CH2=CMe2; however, in the presence of basic donors, the protons are intercepted affording...

Dinitrogen Activation within Frustrated Lewis Pairs Is Promoted by Adding External Electric Fields

“…Since we could not locate the transition states for both the formation of I 2 and Int 1 via direct H 2 addition on P 1 , we do not know the energy barriers for both. Therefore, there is a possibility that I 2 can be observed during the reaction …”

Significantly enhanced catalytic performance of Pd nanocatalyst on AlOOH featuring abundant solid surface frustrated Lewis pair for improved hydrogen activation

“…This indicates that surface defects on supports are crucial for the formation of FLP. [16][17][18] For example, Ozin constructed FLP on the surface of In 2 O 3−x (OH) y through surface hydroxyl groups (Lewis bases) and indium (Lewis acids), demonstrating that the FLPs facilitated the adsorption and dissociative splitting of H 2 in the photocatalytic Reverse Water Gas Shi reaction (RWGS). 19 However, for non-reducible metal oxides, there remained signicant challenges.…”

The impact of Lewis acid variation on reactions with di-tert-butyl diazo diesters

“…N 2 H x , x = 1–4) 23 In a related study, we also reported the reactions of ( t BuO 2 CN) 2 with FLPs, affording routes to boron-carboxylate anions, and FLP capture of diazene (N 2 H 2 ) (Scheme 1(d)). 24 Probing the further reactivity of ( t BuO 2 CN) 2 , in this report, we describe reactions of ( t BuO 2 CN) 2 with 9-BBN, BF 3 and [Et 3 Si][B(C 6 F 5 ) 4 ]. This work illustrates other reaction pathways available to this sterically hindered diazo diester (Scheme 3).…”
