The hydrogen-bond acceptor ability of divalent sulfur in Y-S-Z systems, Y, Z = C, N, O or S, and the donor ability of thiol S-H have been studied using crystallographic data retrieved from the Cambridge Structural Database. Of 1811 Y-S-Z substructures that co-occur with N-H or O...

We proposed genuine HBD/LB cocatalyst for ROPs by introducing 3-amino-1,2,4-benzothiadiazine-1,1-dioxide (ABTD) as a bidentate H-bond donor and triethylamine (TEA) as a mild Lewis base. ROPs of lactide (LA) and trimethylene carbonate (TMC) in solutions at room temperature were success...
The XBeO bond strength is between De=695 kcal mo1-1 for Me3NBeO and D3 = 112 kcal mo1-1 for -bonded N2 BeO. The calculated bond strength for the yet unknown donoracceptor complex Me3NBeO is significantly higher than the strongest experimentally known maingroup donoracceptor complex Me3...

In general, cyclic esters and carbonates contain heteroatoms or unsaturated bonds, which are easily attacked by nucleophiles after H-bond donor (HBD) activation. The presence of a nucleophilic initiator, such as alcohol, enhances the controlled character of ROP. In addition, an H-bond acceptor (...
