Healing by first intention or Primary intention healing happens when the wound edges are approximated e.g. by sutures, staples or glue.. Healing by second intention or Secondary intention healing takes place when the wound edges cannot be approximated and the wound needs to heal from the bottom.. Tertiary intention healing is a combination of both of the above, i.e. the wound cannot be

Practical catalytic cross-coupling of secondary alkyl electrophiles with secondary alkyl nucleophiles under Cu catalysis has been realized. The use of TMEDA and LiOMe is critical for the success of the reaction. This cross-coupling reaction occurs via an SN2 mechanism with inversion of configuration and therefore provides a general approach for the stereocontrolled formation of C–C bonds
