Chem., 2013, 5, 115-121), would be just as favored for Main Group silylene complexes. This result not only shows the range and applicability of the bond-strengthening back-bonding interaction, but also showcases the capacity of silylene complexes to do new chemistry, such as the cooperative activation of carbon monoxide and carbon dioxide.</p>1 aPal, Amrita1 aVanka, Kumar  uhttps://library.ncl.res.in/content/can-silylenes-rival-transition-metal-systems-bond-strengthening-pi-back-donation-0
