In the present work, the regioselectivity for a series of Diels–Alder reactions (4 reactions) has beenstudied using hardness, electrophilicity and polarizability of products.Furthermore,thermodynamicand kinetic calculations have been done. In all results predicted pararegioisomer is more favorableregioisomerinthese investigated reactions.All calculations have been done at the DFT-B3LYP/6-31G(d)...
ON THE REDUCTION OF 4-OXO-4H-BENZOPYRAN-3-CARBALDEHYDES: GLOBAL AND LOCAL ELECTROPHILICITY PATTERNS
A new family of β-diketiminate-stabilized highly electrophilic monomeric aluminium cations with alkoxy substituents have been introduced. The Guttman–Beckett method and hydride ion affinity calculations affirm that groups enhance the electrophilicity these cations. We also illustrate their catalytic application for reactions such as ether activation, hydrosilylation alkene carbonyls. More infor...
