This invention relates to a compound represented by the formula:
where M is a transition metal selected from group 4 of the periodic table;
each R
1
is independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl and functional group, and any two R
1
may be linked, provided that if the two R
1
groups are linked, then they do not form a butadiene group when M is Zr;
each R
2
is independently selected from the group consisting of methyl, ethyl, propyl, butyl, pentyl, hexyl and the isomers thereof, provided that when R
3
and R
6
and or R
12
and R
15
form a 5 carbon ring, then each R
2
is independently selected from the group consisting of ethyl, propyl, butyl, pentyl, hexyl and the isomers thereof;
R
3
is carbon or silicon;
R
4
is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; a is 0, 1, or 2;
R
5
is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, R
4
and R
5
may be bound together to form a ring, and R
5
and R
3
may be bound together to form a ring; b is 0, 1, or 2;
R
6
is carbon or silicon; and R
4
and R
6
may be bound together to form a ring;
each R
7
is hydrogen;
each R
8
is independently selected from the group consisting of hydrogen, methyl, ethyl, propyl, butyl, pentyl, hexyl and the isomers thereof;
each R
9
is independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl and a functional group, and two R
9
groups may be linked together to form a ring, R
9
and R
8
may be linked together to form a ring, R
9
and R
16
may be linked together to form a ring, R
9
and R
11
may be linked together to form a ring; c is 0, 1 or 2;
R
10
is -M
2
(R
16
)
h
— where M
2
is B, Al, N, P, Si or Ge, h is an integer from
1
to
2
, such that the valence of M
2
is filled, and R
16
is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, and two R
16
groups may be linked together to form a ring; d is 0, 1, or 2;
each R
11
is independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl and a functional group, and two R
11
groups may be linked together to form a ring. R
11
and R
8
may be linked together to form a ring. R
11
and R
16
may be linked together to form a ring; e is 0, 1, or 2; where the sum of c, d, and e is 1, 2 or 3;
R
12
is carbon or silicon;
R
13
is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, and R
13
and R
14
may be bound together to form a ring, and R
13
and R
15
may be bound together to form a ring, when g is 0; f is 0, 1, or 2;
R
14
is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, and R
14
and R
12
