In order to draw a Lewis structure of acrolein (C 3 _3 3 H 4 _4 4 O), first we will have to count the total number of valence electrons, which is 22 (12 from C atoms, 4 from H atoms and 6 from O atoms). Two C atoms are bonded together with a double bond and one C atom has a double bond with O atom (carbonyl group - C=O). The articulation of the notion of "frustrated Lewis pairs" (FLPs), which emerged from the discovery that H2 can be reversibly activated by combinations of sterically encumbered Lewis acids and bases, has prompted a great deal of recent activity. Perhaps the most remarkable consequence has been the development of FLP catalysts for the hydrogenation of a range of organic substrates. In the ...
